Charging seems to be slower than on stock. At least that's what I have noticed through using custom roms

Yeah, probably battery degradation or something.
Stay on your rom, drain the battery until phone shuts down.
Start it as often as until it shuts down on its own.
Then charge it until it's full and then start. Your phone.

[Q] Battery lifetime on official OTA Froyo ROM release?

Hi
Any news on how long battery last on the new official release?
Im currently on Pays ROM, and battery last between 24-48 h, with 3g and wifi turned on and daily use of phone, sms and browsing.
Just tried some ROMs that didnt even last a whole day
In 3 hours I have nearly used 50% of battery and that is with 3 short phone calls.
System, cell standby, wifi and phone idle account for 80% usage. Was using a different froyo rom before putting oem one on and did not have this type of drain.
Also not using an app killer as people have been saying that the system can handle the apps, that has not been the case and will install again.
My battery drain has been up massively since I went to 2.2 with the OpenDesire ROM. Phone standby takes most of it. What's causing such excessive usage? Even on the official ROM now :-/
What ROM's are you guys getting best battery with?
You should post on which ROMs you have the battery drain...
I have had massive battery drain on all ROMs until I started using the rooted 2.2 OTA. I would have to charge my phone twice every day but now it's great, I have 65 percent left after a full day of heavy use.
Edit: tried almost every FroYo ROM before this.

Which ROM are you using? I can't decide which one to download
Battery life is also my only problem with this otherwise amazing phone
Maybe it's the rom/radio combination!?
I had PaysDesire v2.3 before installing the OTA 2.2. The battery with PaysDesire with average use went from 100% to like 60% in 12 hours. With the latest one, i lost 8% in 2 hours but with over average usage. Testing the camera, installing apps, setting up things...
That is why I am still not convinced that the battery sucks on 2.2 and I will wait few days (until the shine wears off, as Coldplay would say) before bringing my final decision.

yep ,I now about
you use OTA officiall not ruted
Doesn't you guys' phones' display use most of the battery? For me it's at least 70% of the battery usage.
With SetCpu I use about 1% battery on standby, but as soon as I use it, it drains battery like crazy, even though the brightness is set to 25%...
I am using this one http://forum.xda-developers.com/showthread.php?t=741775
I took it off charge at 7 a.m. an have used it quite heavily today and the battery is still at 50% so I am pleased.
8 Hours and im on 68 %
2 Hours 3D Gaming and browsing 1 Hour.SmS/Few Calls between.
Official 2.2 Froyo ROM.
Wait for Kernel Sources and i think Battery Drain will fall and fall =)

I'll second that. Definitely getting better battery performance on ieftm's ROM than any of the 2.2 ROM's I've used before including Neophytes's, DeVillain, and various others. I've also got much more memory too.

you win the prize for the 1000th desire user posting in the wrong section. The moderators are probably going to win their 100th prize for not moving threads/warning people. And we'll just end up with the 10th thread about battery life scattered in every place.
that aside, no rom or os version has changed a fig for me about battery. It's still good in reasonable terms.

+1.i am getting really good battery performance on this ROM.
but from my experience even from WinMO you will never find a single ROM on which people would agre on 100% that is good or bad.everyone is getting different results.everyone has different apps instaled,using different combination of services (push mail,wi fi,3G...).
Someone will always claim good battery life and others will say it is crap.this is really about testing what works for you the best.
Sorry for my english guys...
When i have a good connection then my battery is ok. After 16 hours i have still 12%. If my connection is bad (i'm in a building) so it search for connection and lost it again i see the battery drain and my battery is empty after few hours...

its not posible to calibrate a xperia s(L) battery , it auto calibrates, if you use battery calibaration apps, it just deletes a important file, (which may have ruined your battery)
i suggest keep letting your battery go to 0% then charing to 100% , the battery will calbrate its self

It might not be an issue; when you turned off your screen, battery was being eaten away and when the screen is turned on it shows the change at that time. Similar stuff happens to the clock.
If you have messed with any system files I suggest you perform a factory reset.

Have you done anything to damage your misc partition? Or do you have a backup of your misc partition? USB bricks are very difficult to get past unless you have a back up of your partition. I believe the creator of 4ext recovery madmaxx developed a fix for the desire that could be used through his recovery. The main thing to remember is that your misc partition is specific to your phone. Not your model, your actual phone in your hand and if you flash a misc partition from someone else's phone it will kill it. Unless you have a backup, or some makes a generic misc for your phone model you may be stuck. Have you tried a ruu, and ate you s-on or s-off?

I was mainly talking about that 100-90 drain... but I'm sure that those jumps after reboots are caused by often ROMs flashes... script that is responsible for creating batterystats.bin just goes crazy... or something like that... my N4 is only unlocked and rooted, everything else is stock and I'm not facing such big jumps after reboot... they're not bigger than 3%

The more you discharge it to nearly auto turn off moment and fully charge after, the better it will work. My was a bit "wild" after I had like 5 ROMs changed in one day. Then it setted pretty nice, keeping up to 3-4 days with normal use. No weird drops, also goin 100-90 smoothly for hours not 2 mins

stock or cm or aosp rom?
Stock 4.1.2
i didn't have that on stock only on cm and aosp
Heeeeey I started to notice this on my stock rom 4.1.2 yesterday after reading your thread :| But you can be sure that it's not a problem since I've bought my g last week so it can't be because of your battery age. It's natural. I think it's impossible to show the correct and exact battery percentage in any OS. To test, you can let your battery discharge to the end and you'll see that the end is sometimes 3 percent (the device goes off when it has 3 percent or more left) and sometimes you get 0 percent but the device is on Maybe that's why percentage is off by default.

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

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.

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!
