Horrible Battery Life after Installing Android! :(

After successfully booting into android for the first time my battery life in android skyrocketed down, but that didn't really bother me.
The real problem is that even in WINMO my battery life is less than half what it used to be, and even after a night (8 hours) of charging (In a wall socket, not USB) its not at 100%
this has me very worried, any ideas? thanks in advance!

did you read anything before you started this thread...........

yes, i did. everyone is having a problem when they charge in android it gets to 90% then they switch to winmo and within minutes it picks back up to 100%.
this is not the case for me, my battery does not jump back up, it drains quickly even in winmo, and when it gets low its not just reading it improperly it just dies, so no this is not the same problem

did you know there are fixes .......and that your problem is not new at all....i am sorry to say that this is a know problem and you would want to ask in the thread of what build you are using and if you really wanted help you would post what build your using and what kernal , but no one can help you at all when you simply state you have battery issues

drain your battery in winmo till it dies, so the battery resets, then charge the battery again till full, it should be allright again.

thank you dipdap i will try that

I strongly advise you NOT to do so. Draining a Lithium-Ion battery entirely is detrimental to its overall life/capacity. So instead of ruining your battery (or going a step towards ruining it), simply turn off your phone, charge it until you get the green LED, boot back to WinMo and it should be alright. If it isn't, look for another way, but completely draining your battery should not be the method of choice.

nobody said to drain it copletely, just till winmo dies, which should be fine. I do this once every couple of months by accident, and have never had a problem. I agree that you should not drain the battery completely though, so, make sure as soon as winmo dies, plug in to a charger.

what rom are you running? I am using shubcraft 1.5 and mine charges to 99% And I can get a full day out of my battery with pretty decent use.
Are you using setcpu cause that could have a major impact also do you have wifi,gps or bt on. I know gps has been known to cause some major drain while in sleep mode.
There is also a thread where people are trying to find solutions to the high amount of drain in the development forum.
We use current widget to create a log and monitor Our drain. You should be seeing less than 10ma while sleep I usually see between 3-7ma while sleep
Funny how when you are watching your battery it drains faster. When you are watching the clock time goes slower.

You can look at this thread

It was very helpful for me to identify how much current is being used while in sleep mode and active.
Download "current widget" from market and monitor your current supply for 30 minutes during your phone's screen is off.
Yeah with the screen off you cant see any thing but thankfully the log will be written for the current widget every min.
If your current comes out to be bellow 10ma during this time then you are doing good and should last you one day of usage else you need to pinpoint what is drinking all the juice even while your phone sleeps
Read the thread ALL OF IT, it will help you understand better.
Cheers.

alright thanks for all the help guys, the battery drain actually worked although i felt strange doing it, but still my android life isn't so great, i would love for it to work completely though because the only wquivalent option on my carrier is the Captivate (Galaxy S) and that thing is ugly compared to the HD2

such problem
I have such problem with battery drain under WM, after i run and quit android, but i found a solution, just pull out your battery few times next just recharge it and it will be OK .

[Poll] Who else has heavy battery drain when shut-down tablet is connected to dock?!

I am aware that there's already a thread that is related to the tablet/dock battery drain. But I thought I'd make a poll to get an overview on the number of dock owners that are affected by this problem.
This thread is not meant for general discussion of the topic, for that please post here.
Even though the battery draining issue is also remarkably high when in standby, please vote only for bundles that drain when they're completely shut down! This will help to exclude every bug that could be software or ROM related.

Where are the over a week or 1-2, 2-3 week options?

I don't think my drain is out of the ordinary. I have a had a couple of programs run rampid and kill the battery but it seems OK. I would like to know how to tell the battery state of each? Also I would say that when charging the dock/tablet combined the charging brick gets really warm.

Well, I don't know but I'd call that no unreasonable battery drain. Or do you think this is abnormal?

That's why I only want to list the devices that drain when completely shut down So no apps can run rampid.
To show both of your battery states, use Dual battery widget (also available at the market).
About the warm charging brick, I noticed that too, but I'm not too concerned since I owned a lot of chargers that got this warm while charging...

I'm grabbing the Dual Battery widget...thanks for that tip. I'll check with a full shut down.

[Q] Strange and inconsistent battery drain

I wouldn't exactly call this an issue because it doesn't really affect how I use my phone - it's merely something odd that has me curious if anyone else has it:
If I charge my phone all night, and plug it out at 100%, then no matter what I do it'll stick to 100% for a long, LONG while before it hits 99% - we're talking..25 mins of sat nav, and spotify, and full screen brightness on the go. But then, it falls down into a more regular pace of discharging.
If however I unplug it 5-10 mins after it hits 100%, it starts discharging normally.
I think I can get a batter life of full browsing of 6 hours, probably. Maybe a bit more (never tried it, never needed to).
I am just curious why this happens with my LG. Do you think it's a fault or is it fairly common?
Thanks
P.S. - testing it again now - 15 mins in youtube watching a video, still at 100%. very strange

you seem to have found some interesting sweetspots of charging and battery depletions.
My instinct tells me the discharging and the 100% mark is influenced by code in some way other then the battery being truly at 100%. There is software like android tuner or battery widget that monitors stuff.
however a great dev already wrote something about tinkering on lg's side in reporting the battery. Which means the percentage is. indicative but completely reliable. To gain more indepth into the actual battery usage other apps are needed. If have battery ocd that is.
I would report this to lg, just to be sure nothing else is happening

what is more interesting is that this happens to me both on official LG, and on ROM (cloudyfix).
Continuing with my tests, I have been running youtube on repeat since unplugging and monitoring. I am now at 50%, with...close to 5 hours of usage?

then its playing from buffer and not continiously downloading and streaming right?

It downloaded all times. I plugged the phone in to charge at 10÷.at that time I had 7:30 hours YouTube screen time on auto at 90÷ . I suppose this is a good performance?

its great performance

yeah i thought so.
So I'll leave with that little flaw I think, I'll just learn not to mind it and be sure to always charge overnight to get the best next day. Thanks for the help

I usually charge my phone and reboot it right after it hits 100%. I don't disconnect the charger until the phone restarts completely.
Doing that I get outstanding battery life

Fix For Battery Jumping Around

1) Charge ur phone while off untill u reach 100%
2)Remove the battery but dont unplug the phone from wallcharger
3)Reinsert the battery, you will see 0%
4) Let the battery charge, when reach 100% power on the phone without unplugging wallcharger.
Now should be all good

you are kidding right ?

This is the one of the worst advices I've heard..... Overcharging the battery is dangerous.
It will actually degrade the batteries performance

I don't know what to say. Does this work?
Also by battery jumping do you mean those crazy drops between reboots or just drops due to lack of deep sleep?

U know how the LIB works? How Android manage the battery?
Try yourself and see! This is not overcharging

Btw the drop between reboots

Battery bin tracks the battery usage giving an estimate of the charge been used, battery .bin gets wiped every time it get to 100%, and the tracking of battery's current starts
As I remember lithium batteries charge in two cycles
1- constant current
2- constant voltage near the full capacity.
But then if you trick the phone to read battery as 0% then you are sending more current to an already full battery overcharging.
The jumping of battery percentage is because a bug in the battery "gauge"
But as always if in wrong, my apologies and I'll be more than happy to read your source.

Biggest issue is that the battery has a very poor C-rating, and has huge voltage drops under heavy load. The reboot battery problem comes from this; when you reboot your phone, or other times as well, the heavy usage spike drops the battery voltage down. Android system them detects this low voltage and just assumed the battery is almost empty. Normally there is some averaging going on to remove these spikes, and even then the battery % only goes down, so when the voltage recovers it just shows the same % for longer. Problem when rebooting is that it only sees this low, under load voltage and acts accordingly.
If the voltage isn't low enough so the phone shuts down, you might get 30minutes of screen time while the battery is showing 1%.
My problem is that the last 14% of my battery lasts under a minute before the phone shuts down. So I just treat 15% as actually meaning 1%.
Also, you can't dangerously over charge the battery, it has protection circuitry built in, and the li-ion charger part will detect the real voltage. This "supercharging" does however cost some long term lifetime from it, so it shouldn't be done too often.

Please excuse me, this is long.
Hello guys. I need some advice. I use I9195.
From the past 2 weeks i am facing serious battery drops
while phone is in standby.
I must mention that in the last 2 months my phone accidentally dropped onto marble floor 4-5 times.
Each time i checked to see if everything was working and everything did. But from the last time i dropped i began to notice this battery drain.
I made sure all hardware is working.
No problem with display even after all those drops.
(only minor scratches)
Earpiece, 2 cameras, speaker, mic, wifi, bluetooth all work fine. Network quality is great. This is the behavior with any rom, any modem and any usage.
When in standby, battery drains upto 2-3% every hour.
No background apps/services , wakelocks or anything that keeps device awake. And yet the drop is steep and is solely due to "cell standy".
I have no screenshots but here is a scenario :::
From 98% to 33% in ,
16hrs usage, 1hr33min awake and 1hr16min screen on.
Wifi enable half the time and 3g data was disabled.
EDIT :: New battery did not solve this drain.

Hey guys. Please suggest what should i be doing.
Read post above. Can new battery help ?
Thanks. [emoji29]

Same problem here i also need help.
From GT-I9192.
My phone dropped 5-6 times and .org works fine now.

Typo

my 6p dies when it's around 15-30% of battery

I have been trying to find a solution to my problem from quite sometime now.
When ever the battery percentage goes below 30% it suddenly drops to 15% and shuts off the phone in 10seconds or so. It happens very quickly.
I don't think this is due to some software as i have tried almost all stock roms as well as custom roms.
Battery drops insanely fast! Anyone else facing this too?

Yesssss! Same thing, it's so annoying, I was just about to post this, let me know if you find a fix for this, I've been looking at like wake lock detectors and using greenify and all that, but there's definitely something wrong with the software, I also tried a bunch of different roms and kernels, idk hopefully someone knows something about it

Have battery replaced (either by Google or Huawei depending where you purchased it from)
It's due to voltage dipping too low at lower percentages. Defective Battery
