Dennis, Though I am speaking from a rumor point of view, I hear the Droids by default have some unnecessary (depends!) processes running in the bg that lead to this quick depletion of battery. Maybe you should check those out first and see what you can disable, then give us feedback. They have been discussed on this list before, but the archives are not easy to search but you can try ... -- Best regards, Odhiambo WASHINGTON, Nairobi,KE +254733744121/+254722743223 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ Damn!!
heavy usage = 3G/Wifi+Gmail+Twitter+FB+Google Talk+Music player even when you disable this when you are not using them, its pretty much a drainer
So is this fact or fiction...or some of those things competition churns from the rumor mill? Dont drink and type :-) On Thu, Jan 27, 2011 at 10:56 AM, Dennis Kioko <dmbuvi@gmail.com> wrote:

I got those stats on the first few days when I was playing around with Youtube, Angry Birds et al...but switching to 2G even with relatively heavy voice usage does help - with GMail and Talk still running in the background. I get 36-48 hrs between charges. The phone does remain a bit warmer when running 3G even when idle compared to when on 2G...
I have the Vodafone 845 and its also a battery drainer, have to charge it everyday. turning off background data service extends the battery a bit. On Thu, Jan 27, 2011 at 11:01 AM, Allan <allayy@gmail.com> wrote:

Hello, I have actually done non-scientific tests using 3G and found that the power control algorithms on Safaricom's 3G network are either not working or the feature isn't enabled. I did this test with a friend. We used a 3G phone heavily on the Safaricom network and used the same phone on Vodacom SA and also Vodafone Germany networks doing the sane amount of data and surfing while on 3G. It was unscientific so don't expect graphs and data rates and all. However, we discovered that the battery only lasted 1 day on Safaricom but between 3 and 4 days on the other networks. So we figured that the power control algorithms were not optimised. In the end, I downloaded some software and run it on a Nokia N97 to check the power consumption levels while on 3G and the app shows it is quite high. So, as much as 3G drains a lot of battery power, in Safaricom's case, it is even worse because the power control algorithms are not implemented/optimized well on their 3G equipment.

Read an article some time back (cant trace it now ) that said the problem is that the guys making the hardware and the guys making the software are from different camps. hence each takes care of his end. hardware guys deliver juice while software guys code for maximum utility from the OS and apps. The result is that there is little emphasis on maximum saving of I/O cycles and perfect sync between hardware and software. That is why Apple, RIM and Symbian devices have excellent battery life. The software is a complement of the hardware. On Thu, Jan 27, 2011 at 2:49 PM, Christian Ledermann < christian.ledermann@gmail.com> wrote:

@Andrew, This is an interesting observation, though with several dependencies.... Poor coverage or an area with no dominance results in multiple handovers and increased power since greater power is required to reach the site peripheries. Also while in SA or Germany were you in one place or kept moving around similar to the way in Nairobi? This has an impact. Power in UMTS is very important as a phone transmitting at high power interferes with the surrounding mobiles. Power control messages are actually sent about 500 times per second to make sure no interference occurs. But the actual action as to whether to increase or not is based on whether the messages received are a certain number of consecutive increase or decrease power messages. Interference reduces the capacity of a site....and this is the real bargain for Operators is...and a nightmare for optimization engineers... ./bernard On Thu, Jan 27, 2011 at 11:21 AM, Andrew Wafula <awafula@gmail.com> wrote:

One way of increasing battery life is by reducing cpu frequency. I think Huawei overclocked the qualcom processor to run at 600Mhz rather than 528Mhz. Laptops have under-clocked processors so as to save on batter power. You can use z4root (z4root.1.3.0.apk) to root your phone and SetCPU (setcpu_2.04.apk) to change your clock speed and profiles. For instance for my ideos a) on screen off = 122Mhz b) on screen on = 600Mhz c) on battery < 50% = 320Mhz you also have to shut down background services for better performance etc....etc
Hello Bernard, Actually in both places I was more or less in one place. During the day time I am in the office in Westlands and in the evenings at home. Germany: During the day was at the office, evening at the hotel/around town South Africa: During the day in the office, in the evening at the hotel In all places 3G coverage was quite good, getting the full 5 bars at all times. Now, the study was very unscientific in the least, but the great disparity in battery life points to some other problem other than the phone. On Safaricom's network, the battery hardly lasts a day, on the other networks 3-4 days. That does raise some eyebrows. At one point in time my colleague was tempted to buy a new battery till we did this test and discovered that the problem wasn't exactly the battery.

It was unscientific so don't expect graphs and data rates and all. However, we discovered that the battery only lasted 1 day on Safaricom but between 3 and 4 days on the other networks.

@bernard: From your agrument it would mean that all Safaricom 3G coverage is poor. Coz it really doesn't matter where you test the phone, the results are the same. Town, Kileleshwa, Westlands, South B, Kilimani, around Yaya Center. It can't be that all these places have poor coverage or I just happen to be in areas that all have poor coverage. If it were one or 2 locations, possibly, but all over..... there must be more than just poor coverage.

In all places 3G coverage was quite good, getting the full 5 bars at all times.
Now, the study was very unscientific in the least, but the great disparity in battery life points to some other problem other than the phone.

Power in UMTS is very important as a phone transmitting at high power interferes with the surrounding mobiles. Power control messages are actually sent about 500 times per second to make sure no interference occurs. But the actual action as to whether to increase or not is based on whether the messages received are a certain number of consecutive increase or decrease power messages.

Hi Andrew, An experts view on this is that there are parameters that can be fine tuned but they vary depending on the subscriber population size and density.A gamble has to be made in coverage and cell-size...there's only so much equipment (Node Bs,etc) you can pack in an area....Initially, you should make sure that your 3G radio network has CELL_PCH or URA_PCH state in use, and that the T1/CELL_DCH and T2/CELL_FACH timers are reasonable from battery life view point. These small changes will improve battery life in all 3G devices. Going forward you can enable group of HSPA+ features that are generally known as CPC i.e. Constant Packet Connectivity. CPC includes, among others, Discontinuous Transmission and Reception (DTX/DRX) that will significantly increase battery life in compatible HSPA devices. For those around Thika road, and with the enhanced modems (going for 10k at safcom shops)or HSDPA phones, should benefit from this. All of the above are related to packet data only. For extended talk times, you may want to take a closer look at CSoHSPA (Circuit Switched voice over HSPA). All very easy on paper I might add... ./bernard On Thu, Jan 27, 2011 at 4:16 PM, Andrew Wafula <awafula@gmail.com> wrote:

I might add that, power consumption was one of the trade offs on standardizing UMTS or wait for HSPA+ and Enhanced LTE....as marketing forces rarely wait technical enhancements, 3G was unleashed...and your experience is testament to that... R&D fellows claim that power consumption is significantly lowered and high priority in Enhanced LTE and HSPA+ standards...It should be.No one wants to carry a 500g lithium battery-pack to power an LTE device... ./bernard On Fri, Jan 28, 2011 at 10:03 AM, Andrew Wafula <awafula@gmail.com> wrote:

Hello Bernard,
Actually in both places I was more or less in one place. During the day time I am in the office in Westlands and in the evenings at home. Germany: During the day was at the office, evening at the hotel/around town South Africa: During the day in the office, in the evening at the hotel
In all places 3G coverage was quite good, getting the full 5 bars at all times.
Now, the study was very unscientific in the least, but the great disparity in battery life points to some other problem other than the phone. On Safaricom's network, the battery hardly lasts a day, on the other networks 3-4 days. That does raise some eyebrows. At one point in time my colleague was tempted to buy a new battery till we did this test and discovered that the problem wasn't exactly the battery.

@Andrew,
This is an interesting observation, though with several dependencies....
Poor coverage or an area with no dominance results in multiple handovers and increased power since greater power is required to reach the site peripheries. Also while in SA or Germany were you in one place or kept moving around similar to the way in Nairobi? This has an impact.
Power in UMTS is very important as a phone transmitting at high power interferes with the surrounding mobiles. Power control messages are actually sent about 500 times per second to make sure no interference occurs. But the actual action as to whether to increase or not is based on whether the messages received are a certain number of consecutive increase or decrease power messages.

Hello,
I have actually done non-scientific tests using 3G and found that the power control algorithms on Safaricom's 3G network are either not working or the feature isn't enabled. I did this test with a friend. We used a 3G phone heavily on the Safaricom network and used the same phone on Vodacom SA and also Vodafone Germany networks doing the sane amount of data and surfing while on 3G. It was unscientific so don't expect graphs and data rates and all. However, we discovered that the battery only lasted 1 day on Safaricom but between 3 and 4 days on the other networks. So we figured that the power control algorithms were not optimised. In the end, I downloaded some software and run it on a Nokia N97 to check the power consumption levels while on 3G and the app shows it is quite high. So, as much as 3G drains a lot of battery power, in Safaricom's case, it is even worse because the power control algorithms are not implemented/optimized well on their 3G equipment.

@Ndungi. I have thought about flashing my ROM since I got my android. Its not the IDEOS but HTC and I love the mysense UI it came with. If anyone knows where I can get a ROM for HTC glacier with the sense UI or similar i would be more than happy to flash it.

3G Utilises battery power to near 100% utilization. Same applies for Blackberrys' EDGE works well. On settings please set the parameters on the Ideos as follows. Go to Settings then choose Wireless and networks and choose Mobile networks Disable or Uncheck Data enabled and choose Use only 2G networks. This will save you On battery usage. Also disable GPS found under security and Location. So far I have disabled these features and my battery has worked just fine giving me the maximum use of the Ideos Android phone. I am not sure of what works for you as far as using your Ideos Android phone is concerned. Those are the few I have interacted with. Cheers.

Daktari Matt, We are on this issue pretty much *after* changing the settings you've described. I believe the solutions on the xda developers forum (setcpu etc) will give you mileage over and above whatever you have achieved.

You can get the Nokia DC 11 Charger if you have a compatible phone with the new mini-usb standard, like the Huawei IDEOS range. The portable charger so far is able to charge my current IDEOS up to 50% ?(doesn't go to 100 for some strange reason). You can charge on the go and it can re-charge a couple of times. http://plixi.com/p/78277396
I used to have a similar charging problem, I updated my Xperia x10i from android 1.6 to 2.1 and now I can charge to 100% also for power management, download an app called green power, works really well. I use my phone heavily and it still lasts me the whole day. David.

The portable charger so far is able to charge my current IDEOS up to 50% ?(doesn't go to 100 for some strange reason). You can charge on the go and it can re-charge a couple of times. http://plixi.com/p/78277396 _______________________________________________ Skunkworks mailing list Skunkworks@lists.my.co.ke http://lists.my.co.ke/cgi-bin/mailman/listinfo/skunkworks ------------ Skunkworks Rules http://my.co.ke/phpbb/viewtopic.php?f=24&t=94 ------------ Other services @ http://my.co.ke
I have 2.1, I think the issue is the compatibility with the Nokia battery , also ,from the article posted, I really doubt if half-recharges is a good idea, though I noticed it happens when you are using USB (no option to turn USB-charging off)
