Battery Drain

Hi All,
When i look into (almost) all roms i see the problem with the battery drain problem.
To bad i do not have the knowledge to find out what to do.
But i think that some smart developers work together to find a solution about this battery drain problem.
So that's why i start this thread so we can discuss this

AdamG's Official Froyo HTC Sense might hold the key to this since it seems to give about 2 days battery performance with the original battery unlike any other rom.

It would be great if he could share the knowledge
I am using LeeDroid 1.4c and I too experience battery drain issues...

Someone tried this one http://forum.xda-developers.com/showpost.php?p=7170484&postcount=173 ?

Tested a lot of roms with froyo and sense. The roms based on 2.06 base are draining relative more then the roms based on 2.04.
Above is not scientificly tested.

Charge to 100% , go to recovery , advanced , wipe battery stats. Enjoy greater baterry life

I had NONE battery drain problems on any of ROMS 2.1 or 2.2, and i did try alot of them.
Maybe theres something wrong with your phone itself (battery).
But definetly try wipe battery stats in recovery.

Since 08:00 morning had WiFi on.. network Data of... and now 12:02 battery is now 90%. DId have play with config the Tasker Tool (Great app).
Tomorrow i will do the test again but then with Network Data on and WiFi off.

Yup, that ROM has the best battery life by far...

people are having mixed results on the battery perfermance of adam's sensefroyo rom. i experienced a poorer battery life compared to eclair (i used Amer_v4 and the battery was excellent) but can still manage to last a full day usually. haven't tried out the froyo roms though.

btw aren't you're using opendesire?

I've changed about 8 roms, mostly used 4, but can't say there was a huge difference between them. 2 days of normal use, 1 day of heavy use.
Possibly shadowfrost and DeFrost 2.4 had the best battery life and I had the fastest kernel installed...
I would think that - some isolated problem aside - mostly it has to do with some applications/settings

sometimes my E-Mail application is consuming most of the cpu. It keeps the cpu at max frequency. Even if i try to end the taks with the app "system panel" it wont solve the problem. I have to go into the app and make a manual sync.
i also found out that automatic brightness is using loads of battery. since i set it to static I'm experiencing almost 2 days of battery life with moderate use.
I'm on Defrost 2.1

Hello again everybody,
Yesterday whole day online by WiFi. Using phone couple of hours and my Maildroid Email was active without prevent sleep mode.
Battery was empty after almost 17hours. (+/- 5% every hour)
Today. Wifi on. Maildroid now with prevent sleep mode ON.
Have unplugged the phone 4 hours ago and battery is at 75%
Tomorrow i will test this with Network Data on.. and without prevent sleep mode of Maildroid. And day after with prevent sleep mode.
I know for sure.. the battery will drain very vast for both situations...
BUT Ill let you know
EDIT 26-07-2010: Battery was empty tonight on 1:30.
NOW I do the whole test again but now with network data on and WiFi off

Ive had the opportunity to own a Nexus One at launch and a HTC Desire...I always found Android OS to be the issue whenever i had excessive battery drain.
Ive found my issue to center around the OS 'calling home to sync' (whether 'sync' option is selected or not)Initially, the problem was resolved by deleting all my sync funtions...but that was obviously not practical........ so now I keep my GSM data connection running and I get about 2.5 days on Open Desire (non HTC Sense).
AdamG seems like the guy who knows what hes talking about - His changelogs for OpenDesire actually hint at him having done some battery drain tweaking...whatever he did, he has definitely fixed it
Cheers

I've tried so many ROMS in the past few weeks to try to solve battery drain issues. On some, I could almost see the percentage dropping as I looked at the home screen! I even bought a new battery thinking I might have killed the original.
OpenDesire does seem to be the way forward re this problem if you're intent on the HAVS kernel. OD2.3a gave me almost two days of varied use.
However, and I know this is going backwards, an earlier DeFrost - the 2.1, is brilliant for me. I'm now at two days since unplug and still at an unbelievable 45% - yes, I know, I thought it was broke as well! For now, I'm sticking with this one. Everything I want works and I don't have to carry a spare battery in my pocket when I go out.
Hope this is of some help. Don't despair. You will find the one for you.
Cheers

I don't get why everyone says they have such a issue with battery.
I get about 2.5-4 days of use with DeFrost 2.2 and have done about so since DeFrost 0.9. I've had it up around five days once.
How are you actually using your phones?
It's not a "Froyo" issue.

It's very interesting to me how are YOU using your phone?
Come on, 4 days ? When i talk about 30m to 1h each day and using a phone little bit, i have at least 30-40% down.
u mean u only drain about 25% each day? are u actually using your phone ? wifi, calls, 3g ? or u have a expensive pocket toy just to show to your friends ?

I think you need to download "Battery Calibration" app from the market, that will do the job.

I tried that but that also doesn't seem to work

[Q] I tried everything but my phone still shuts down at 20%

Hello im on cyanogenMod 7.2.0.1 stable build.
i had a lot of rom's before and always the phone shut off in 20% i read and Implement most of the guids here on how to calibrate and do stuff to fix it but without any succes, if anybody have idea it will be great thanks!!

I had the same problem,I think it was due to the battery itself being worn out, a new one was bought a couple of weeks ago, I've not run the phone down below 7% yet to see if it reaches 0, but it's already much better than before.
Before buying the new battery I tried various calibration techniques and apps, none worked.

tnx for your fasr replay i think i will buy a new one thanks!

I have used the "nexus one battery calibrator". Someone posts a nice how to. Search for "Advanced Battery Calibration for HTC Desire and Nexus One on NON-SENSE KERNELS". The important spot is ... "Make the calibration permanent (thx to user "theGanymedes"):".
Needs root.
Before it shut down at 10%. With a calibration it will be at 1/2%. It works for a half year, then you have to do it again.

Battery serious problem

hey guys,i have been flashingmany roms every week for about 2 months, then I decided to start fresh.
wiped every thing via cwm and then flashed stock rom via odin,then rooted it.
problem is battery is as fast as HELL , and i have sudden drops, e.g. phone shuts down suddenly at 30% or even 50% , and when i connect charger it shows 0%.
tried battery calibration but no good.
I bought a new battery , and my phone still have sudden shutdowns when used for more than 30 minutes.
even offline.
Is my phone damaged ,or it has permanent leak ,even i change batteries?!
plz reply ASAP , and btw i dont have a screenshot cuz i am using stock 2.3.6.

I recommend you to go to a Samsung Costumer Service and ask for help. I think is a hardware issue, not a software issue.
Also, to use screenshot on GB, use Volume down + Home button.

Must be hardware. If the battery change doesn't quite cut it, then its a hardware problem.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?

Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.

Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...

Will be an app causing your phone to wake

I dont know...i searched on the web and someone said that stock kernel have some problems

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?

I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...

You have problems with motherboard. Go to service center to replace it on waranty.
Powered by CM12.1

But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!

Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.
Powered by CM12.1

How long does yours battery last with some normal usage?

Almost 3 days with moderate usage.
Powered by CM12.1

Woww thats a very big difference haha.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.

Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!
