Hello! I'm having serious problems with my battery. Since I installed CM10 my battery just goes from 80 to about 60 or 50%, then it drops again from 40 to 20%. Already tried to calibrate with battery calibration app, or this methods, done full wipe (did the process from the beggining, back to Cm7 and no results at all!
Pictures attached.
Please, pleaase help! I'm selling my defy, and do not want to sell it with this issue.
PS: Original battery

After checking the ownership in root explorer or simular apps, recharge to 100% and let it sit for a couple of hours. Do that again after discharging it.
You will probably be selling a worn battery anyhow, but then maybe with a calibration so the percentages work. This is mostly due to changing with a fast-charger (not the stock one) or charging it not often enough. If you have the habit to let it go to 0%, then it is worn in less then a year to a degree that it last for a couple of hours less then in the beginning.
New battery is the only way, I got an anker one off amazon for £5 and have great battery life on cm10. The
above method or a change of ROM may help but the only real cure for me was a new battery

Hello there,
I would really like some advice - my battery is draining like water. I'm quite convinced it is the regulation of the unit; I bought a 2400mAh battery replacement and it lasted ages on first go, but then my G1 started draining stupidly fast after I'd recharged it. This also happens on the stock battery too (buy even quicker!). I'm convinced it is the regulation because a) I've never had battery problems previously and b) the battery meter starts at about 26% when I plug it it in (after the phone shuts off from it being dead and I then plug in the charger).
I actually have a bricked G1 that still charges batteries, so I thought I'd do an overnight charge on the battery that way, to 'remind' the other G1 what a 100% battery is like, but that didn't seem to work either.
Can someone help? Is this a known problem? I would really appreciate any advice.

Things that cause ridiculous battery drain;
Backlight, keep it at no more than 30%
Wifi - turn off search for open networks,
Gps - wow does this drain

GPS doesn't really drain battery unless it's actively being used...at least not on my phone.
You can also try disabling 3G if you're not in a 3G area. It will keep trying to find a 3G signal, which really drains battery.
For the record, I have a stock battery that I get ~13-16 hours on from a single charge... my backlight is at 40%, GPS is always on, and I use wifi whenever I want to surf the web and am near an open network.
OP...if your battery is lasting you only a couple of hours, then I'd try to reflash your ROM. Might help...
Wow 13 to 16, I am lucky if I get 6 with 30% backlight, and wi-fi and gps off, I have always gotten that on ever rom even stock with no widgets, you are one of the very few with good battery life cause I have seen many complaints about short battery ranges

Yeah, that's on a normal, moderate usage day. If I use it heavily, with a lot of wifi and web browsing, then I'll get around 10.
Maybe your battery needs to be replaced... could just be old and not holding a charge properly.
It's 2 months old, has done it from day one, I also have another battery that does it too that I kept from a previously brick g1, so one 3 phones, all the same battery life but then I use it quite heavily, always browsing on the web since my computer burned out

try that? 3rd gen battery could help..
Thanks for the suggestions, but it's not a wifi/3g/brightness etc problem - I've had a G1 for six months, I know exactly how much power should be consumed. It's also not the battery; I have two stock batteries and a brand new 2400mAh battery, which for the first few charges lasted about 2 - 2.5 days and was brilliant (as it should be), but now doesn't last all that long.
I may have made the situation slightly better however - I did a Nandroid backup, wiped to factory (well, Cyanogen 4.0.4 anyway) and booted into that. I then restored the backup and when I plugged back in to the charger, the meter was at 85%, and seemed to take a normal amount of time to charge (and not jump to 100%). It remains to be seen if the problem is solved, I've yet to have the battery drain (this is a good sign though) an plug in the charger to see if it will jump from 0 to 25 or not.
I'll re-post when I know.
run the battery down until the phone shuts off without plugging it in.
charge the battery while the phone is off over night
do this 3-5 times and see if you get any improvement.
also remember some of the cheap 2400 batts from ebay and such claim 2400 but that is from 3.5V to 3.0V. The G1 considers 3.2V to be dead so you only get from 3.5V to 3.2V which sucks.
I'm with gridlock on this one. My batteries suck. It always needs a mid day charge. And to the poster that said to reflash a rom, that is bad advice. There is known issues with getting poor performance out of these batteries. I have 2 and both do the same. Got the second one from complaining to t-mo about how bad it sucks.
Reflashing seems to have worked...the 2400mAh battery seems a lot better now, it lasted nearly two days (it runs at 3.7v, according to my battery diagnostic), I've only just recharged it last night. When I plug it in, it charges normally and linearly now, instead of jumping straight to 25%.
So my advice, if anyone is having similar problems to me, would be to try a reflash.
Thanks for your help everyone.
So i recently flashed CleanDFT ROM, first couple of days the meter read out 1 day and 18 hours which im very surprised then it went down to 1 day and 4 hours, now this morning i unplugged and it tells me i got 19 hours left from full charge, should i go by this? or is there something wrong?
hello can you help me wid flashing...i came from android...no idea of how to do it...

Redirecting you to the right place.
If you have just flashed a new rom, in general, you need to go through a couple of battery cycles before the battery read can be accurate. I remember when flashing my ATT FUze I had to wait 2-3 complete charging cycles ie. discharging battery to 10% and charging back to full before I could get accurate reading. If you are experiencing worse battery time than before flashing after 2-3 cycles you might need to reflash the rom; you should see better battery time with custom roms, so I have heard.
I also wouldn't go by the battery saver timing, I would go by wpbench or real time use to get an accurate reading on battery time. I have a 1800 mah battery in my focus and it reads 24 hours on battery life
As far as i know, doesnt all the ROMs have basically the same battery life?
Ill be going out of town sometime this week and ill be out most of the day, i need a rom thatll at least last a whole 12 to 14 hours at the most or whole day at best of just occasional twittering and occasional checks on facebook and probably capture some pictures and a video and maybe an hour at most on music? im sure this phone can handle it but idk what you guys suggest
I have the same issue with ATT samsung focus with Roger latest updates, the battery meter is just not accurate, sometimes full and just reboot upon eject from the micro usb. The battery was fine until recently. Found a few other with the same issue online, no solution available yet.
*pulling out battery doesn't work*
The solution is exactly the same as it is on a laptop.
Lithium ion batteries, and, actually, come to think of it, pretty all rechargeable batteries lose capacity over time. The phone, to begin with, doesn't have a good idea of how much capacity is left, and it has to estimate based on previous performance. This is partially a result of battery manufacturers going as cheap as possible with the circuitry in lithium ion batteries.
The phone needs to figure out how old your battery is. This data is definitely lost with a new rom. Leave it to charge overnight, then unplug it and let the battery run all the way to dead. Charge it again, and your battery percentages should be correct. It may take more than one cycle, but the meter should settle into a correct estimate eventually.
Incorrect battery stats are a possible reason for fluctuations in battery life and reseting them as described in the previous post can help.
Another thing which you can do is use an app like this http://forum.xda-developers.com/showthread.php?t=1328730 to check the reported mV rating of your battery at full charge. That can serve as an indicator of the battery life you can expect with your current battery stats.
Battery calibration, galaxy tab 2 CM9CM9, and at first glance it seemed that the battery was draining way too fast.
So after some research, I found a solution to this problem. When I had the stock rom, the battery life was like 15 hours, all day wifi on. But when I moved to cyanogenmod 9, the battery life dropped drastically to about 6 hours, minimum brightness levels. So got back to stock. Soon I was missing CM9
Suddenly came to my mind that maybe the problem wasn't CM9, since I have read that many people is very happy with battery endurance.
When we flash a new from, the battery data remains intact, this sometimes causes the new rom to have a bad reading of the stats.
The solution I found is battery calibration. You can find an app for free in the market. What it does is, it wipes your battery data so the new rom generates fresh data.
You just have to get your GT2 fully charged, then calibrate with the app.
Since I did this, I feel battery life has improved, in fact, I think it is better than before CM9.
YOU SHOULD GIVE IT A TRY.
it worked fine for me. :laugh:
sorry
The post was right before sending it.
Tried to attach a pic, but I'm new here guys
Battery calibrate only deletes the existing battery usage data. It gives you a fresh look at what is draining your battery. This has been argued many times in just about every other device forum. Here is the answer from the google rep.

:good:
I have an i9505 running resurrection remix 5.5.6 with alucard kernel. all was going ok-ish until I used the battery calibration app to delete the batterystats.bin file. since then the battery will only charge up until the high forties or low fifties in percentage terms. the battery was fully charged when I calibrated it, it's really getting on my nerves now.
could it be a kernel thing ? I have fast charge enabled in alucard...
any help would be appreciated !!!
1. Do not use battery calibrating apps. They are useless. They are for old phones and are useless now.
2. Deleting batterystats is useless. Do not do this anymore. Android can take care of it.
3. You can try a diffent ROM/kernel. Maybe that wil fix it.
For the future let Android handle you battery. It's perfectly capable of doing that.
Even on older phones battery calibration apps were useless, because Android always deleted the batterystats.bin file when the battery was charged to 100%.
OP, contact Anker and see if they have an app to reset the battery percentage. Some companies, like Mugen Batteries, offered such an app because the device itself couldn't recognize when the battery was at 100%.
I manged to get it fully charged today and I'm wondering if it's related to alucard kernel as this only seemed to happen when I was running the first two cores at different values from the last two.
be interested to hear if anyone else gets the same thing if they recreate settings like that...
still, I'll look into that anker app angle. I also have a zero lemon battery that doesn't seem to give it's proper capacity. personally I think Samsung Androids are quite poor with batteries in general, like your percentage going up after you've put the phone down and stopped using it, or the last 2 % lasting longer than the previous 20 (on extended batteries at least)...
Hello everyone.
(Please excuse my lengthy post, I had a lot of details to share. Thanks!)
So I recently bought N910C from a guy in Dubai, who gave me an extended 8500mah battery along with it, and claimed that it would last me 3 days easily (though later he claimed that it runs a day on full use, and 2 days no mild usage. Also claimed that standard 3220mah battery lasts less than 6 hours) but 8500mah would take around 6 hours to charge (it takes me 1.5 max, does 1% in a minute, with quick charger). I was however instructed to calibrate the battery properly, which I did, twice, tried the manual (draining and full charging) method, and also tried two apps: Battery Calibration and Battery HD.
Facts:
After buying, I flashed marshmallow stock rom for N910C and rooted with CF-Autoroot.
I have been using its own fast charger throughout, not the standard charger.
Here is the problem:
Before rooting and changing the rom, the battery was barely lasting and would shut down when around 30%. So I rooted the phone and did the calibration (manual+Battery calibration app), but the battery timing remained the same, or maybe increased slightly. The good thing was that it did not shut down at 30% and went down to 1%, where it stuck for good 15 minutes (with me browsing the net).
After I recharged it, I tried Battery HD app, which ran tests and gave me the following figures of battery usage:
30 minutes on internet: 5%
30 minutes on video: 6%
30 minutes on music: 2%
After this process, the battery again collapsed in its 30s%. I tried the battery calibration method again, but no luck now, battery collapses in its 30s. The guy who I purchased it from keeps sharing the snapshot and claims it was working fine before.
Now my questions:
I read some guides, including topics on XDA that suggested that Exynos drains more than snapdragon. So should I try to make a switch to a variant of note 4 with snapdragon, or would that make no major difference?
Is this battery faulty and I should change it? the Seller claims that he had to come on to an extended battery cause the standard was ****, so I shouldn't try and get another, it would be a waste.
What could be the problem if the battery falls in 30s% even after calibration, with exception to that one time?
Also, when it collapses in its 30s and I put it to charge, the screen shows "charging at 45%", why is that?
Lastly, I read here on xda that zerolemon extended batteries require the standard charger as the quick charger would give **** time and would charge them quickly. Will that apply to me as well? Although my battery isn't zerolemon, it's some unknown brand. And it seemingly charges quite quickly with the regular charger as well (when the phone is turned off).
He claimed that it should take my phone 6 hours to charge, it takes me barely 1.5 hours even on the extended battery, is there something I am doing wrong?
If you went through all of what I wrote, thank you for being so patient! So now, do I have any hope with this phone or should I just sell it off and maybe get an AT&T or T-mobile variant?
Thanks in advance for the guidance to come. I'll keep updating this post with whatever other tests I run, and the progress.

Sounds like the battery is faulty. ...try another one if possible

That's what I am trying to do, if only I can find someone's spare to try out lol.
p.s. you signature, lol I have the same three phones with the same status, except that my G3 (which is also white) is in a coma and G2 is up for grabs.
