I have 2 mesmerize phones and applied the official uscc ec10 update to both of them yesterday. One device's battery performance since the upgrade has been horrible. It will go down 20% the first 30 minutes and only get about 15hours of use before the battery is completely dead. 88% is display. The other mesmerize is healthy and usually has cell standby as the top battery use. Neither phone is rooted at the moment but it is not out of the question. This was not an issue until the update. Does anyone have some suggestions to try and resolve this issue?
I had a similar issue. My phone was using 10%/hour.
However I'm using the EC10 that is available thru this site.
I ended up re-flashing to correct my issue.
Not sure if we can re-flash the stock release from uscc.
Also you may want to disable wifi, and gps. Those tend to be battery intensive.
Here is the link on how to get your phone back to stock:
http://forum.xda-developers.com/showthread.php?t=881064
Make sure you have the right usb drivers for your windows O.S. so that ODIN can properly
communicate with your phone.
There are way more capable members here that I'm sure can offer other ideas to try. Hope you get this issue resolved.
Cheers!
You can flash the stock release from us cellular, if you already installed the leaked ec10 if you flash the stock 2.1 files from the forums here with Odin first. And obviously you disable voodoo if you have it enabled.

drain the phone to as far as it will go and then shut off.
leave it powered off and plug the phone into a computer usb port NOT the wall charger.
let the phone charge up until it says its full.
unplug it for 30 seconds.
plug it back in and charge it til it says full
unplug it for 30 seconds.
plug it back in until it says its full.
do this 4-5 times.
power on the phone.
charge it until the phone says charged.
unplug it for 30 seconds.
charge it again.
do this 2-3 times.
(alternately if you rooted and installed clockwork recovery just wipe battery stats, and use the regenerate recharge method i just mentioned)
come back and let us know if your battery life is different.
after you do this once ALWAYS drain the battery to 10-20% before you plug it in.
charging the phone too soon can damage the battery.
battery makers, and the industry as a whole claim that these batteries have no memory, and i can tell you for 100% fact that if you charge your phone like some drunken lunatic the battery will suffer for it.
what you are doing is forcing the battery to relearn what full battery charge is.
using the wall charger is the worst kind of charge you can use on your phone.
it is ONLY meant for a quick boost charge and is harmful to your battery if used as your only charge source.
the batteries in cell phones now days are best charged with what is known as a "trickle charge".
wall chargers are typically 1amp, and charge the batteries too quickly.
anything over 500ma (a USB 2.0 port) i have found to be an unreliable and piss poor charge.
anyone who disagrees should stop and learn a thing or two about batteries and proper charge methods.
Not to mention judging battery life 24 hours after installing a new OS is a moot point. Give it a few days people, then start judging. When the undervolted kernel is released, we will have no battery issues like back in 2.1 anyway.

yup 100% agreed, anytime you flash a new rom it will completely jack with your battery stats.
that is why you need to wipe battery stats anytime you flash a new rom.

Ok, so I've been experiencing this for the past few weeks now, and I'm getting sick of it. I plug up my phone to charge it overnight, or just to charge it when I know I will be in a place for a while. After a while, the phones battery will say 100%. But when I take the charger out, the battery isn't fully charged. It IMMEDIATELY jumps down to around 40% - 70%. I can get it fully charged after unplugging and replugging the charger in, sometimes numerous times of unplugging and replugging. Also, my battery has died on numerous occasions on between 10% - 15%. I calibrated my battery the first day I got it (as a replacement) and got decent juice from it, a noticeable improvement from the old battery. Am I the only one experiencing these issues? Is there a fix for it???
*NOTE* I'm on my 2nd battery (replacement) and this is also a replacement phone. Also running GummyCharged 1.8 GBE on EP1Q, RFS, w/Minimal Gummy theme, if that matters. Also, its not just my phone, my wifes Charge phone has the same setup and it does it also. So it may just be something wrong Gingerbreak. Never did it on FroYo. Gonna Odin back to FroYo and report back.

This is because you cannot leave the phone plugged in to charge for an extended period of time. Once the battery reaches 100%, it stops charging. It will start charging again later, after the percentage goes down to a certain set level. This is why you have the huge initial drop-off after taking it off the charger. If you want to leave the phone plugged in for an extended period of time, turn it off and plug it in to allow it to charge, then it won't discharge as quickly. Otherwise, this is normal behavior for all android phones, and trying to make it so that the phone stays at 100% full charge is bad for both the battery and phone.
I've been having some strange problems. My phone will die with between 4-8 percent battery left. I can turn it back on and once it drops another percent or two it will turn off again. I have calibrated it and my battery life is good but this is a strange issue. Upgrading to rc2 today.

I have the exact same problem. It will just go from 50% to 100% in a second and then unplug and plug back in to make it work. i haven't been able to figure it out either. 2nd phone and 2nd battery as well with same issue. I guess it has to do with my habits somehow.

I believe the use case he is suggesting is a little different than what you are describing. When the phone is plugged in at say 12%, it charges for a while and gets to say 63%. At that point it jumps to 100% immediately. The phone must then be unplugged from the charger and re-plugged in and then it will continue properly to 100%.
Hopefully that is a little clearer.
I mean, usually I turn it off to charge. And I have that No Moar Powah app installed. So I set it to reboot at 100%, it does and when I take the charger out, it immediately drops to between said percentages. almost like clockwork. Very annoying. I understand what u mean Imnuts, but my Vibrant, HD2, or others never experienced this issue. Also, my first Charge, would keep a charge if I left it on the charger once it hit 100%. Maybe an issue with the charger itself? A Verizon rep told me to bring in the charger itself if the issue persists.

Almost exactly my issue. I'm not understandings what the problem is. I'm assuming u have that issue also???

Hmm i have the opposite of that problem every time i unplug my phone from charging overnight the battery meter would always read 100% never below that.
Also does anyone know which battery meter i should follow for battery calibration? The battery meter in the status bar, the battery level in system settings/about phone/status, the battery percentage at the lock screen or the battery meter on the screen when the phones off? They're all giving me different readings for some odd reason.
Sometimes I get that too, but for the most part, its the false readings from the lockscreen, and the about phone settings. I may send off for a new phone, run stock for a few days to calibrate my battery then root on a full charge.

I see what you're saying, but on the other hand I charge my phone overnight with no problems. Never did this before, but I don't have time to sit around for 6 hours for it to charge

Well I went back to FroYo GummyCharged v1.9 and lo and behold, the charging issues VANISHED. Charged my phone overnight last night and when I removed the charger, 100%. No drop immediately back down to 56% or some weird number. Maybe its a Gingerbreak leak issue. I've noticed that it only happens to my phone on Gingerbread. Also must mention, my wifes phone does it also. She's on Gingerbread. She complains that I broke her phone lol.
*EDIT* CONFIRMED. 2nd nite in a row, no issues charging.

Imnuts...ill have to disagree with you. This is the only android phone I've had this problem on, and I've had 6 different android phones. also, it only started happening for me when i went to Gingerbread. Going to flash back to Froyo and i will update.

Same here with me. It only started when I went to Gingerbread. Also happened on my wifes phone, also on GB. I went back to FroYo 2 days ago, and boom, no more charging issues. I can leave it on all nite and not get the random percentage drops. I gotta calibrate my battery now.

So it was a Gingerbread bug (GingerBug???) right? My battery life seems way better also. 6+ hrs off the charger and I am sitting on 73%. Not bad for me.

The mis-information in this thread regarding Li-ion batteries is getting out of hand.
I think many of us are thinking about ni-cad batteries in which all the "bad" things we are talking about in this thread apply.
for a Li-Ion Battery, there is no "memory" effect. this means you can charge it at any point during the discharge phase. You also do not need to allow the battery to drain fully and charge to full to "condition" the battery. Li-Ion batteries can be charged at any point up to any point (from 30% to 70%, then 50% to 90%) and it will not effect the batteries performance.
Li-Batteries also do not suffer from overcharging. The charging circuits in cell phones will charge the battery until it is full, and then trickle charge from then on. And because Li-ion batteries do not have memories, this type of charging will not effect performance.
Li-Ion batteries can only be charged a finite number of times. However, the number of times does not translate to the number of times you happen to plug it in. The batteries have a rated number of "charge cycles", this is when the power from the battery has been exhausted and then re-filled. If you always charge your battery at 50% - 100% then every 2 charges you are using 1 full charge cycle. The batteries in the charge are 1600mAh and have approx 500 charge cycles. if you discharged and charged your phone from 0 to 100% every day, your battery would last 500 days before it would start to suffer from poor performance.
the OP in this thread is having software related issues related to the phone mis-representing the correct charge level of the battery, and then stopping the charge cycle prematurely.
Remember, it is perfectly OK, and expected of you to charge your battery as many times as you need to. Keep the thing on the charger any chance you get, it is not going to hurt it, its designed to be used that way. This is why Li-Ion took over as the battery tech of choice compared to Ni-cad.

This coming from a person WHO KNOWS WHAT HE IS TALKING ABOUT is very beneficial to us. Knowing that there is no way to actually "condition" a Li-Ion battery means that us who are actually suffer from poor battery life either have defective units or defective batteries. I hear of this miraculous 2 day battery life, yet I struggle to get thru a full 7 or 8 hrs with moderate usage. And this is a replacement unit AND battery. None of my other phones had that issue of immediately droping percentages like that, so I figured it was a software issue, that's why I went back to FroYo to test it out. Seems I was right. Gingerbread has a software issue that keeps the battery on some phones from reaching a full charge. Also my phone would be boiling hot during the charging process. Since reverting back, I've had no issues. Thanks for the insight. Coning from a knowledgeable source, it means a lot. Thanks!!!

Trying to be a showoff, I decided to let my Blaze drain down to near-zero so I could get a screenshot of the battery stats page in CM. Unfortunately, it shut down when it hit "0" on the battery meter, and when I plugged it in to charge a few minutes later, it came up to the battery charge screen with the icon of the grey battery, and then shut off.
I can get it into clockworkmod and download mode while on AC power or plugged into my computer, but neither will charge it. Upon reboot while off AC or USB power, the Samsung logo flashes for less than a second and then shuts off. No CM boot animation whatsoever.
A voltmeter shows 3.65 volts on the battery, but I'm assuming the available amperage is extremely low and can't provide the required juice to boot it up completely. Any ideas would be appreciated.
boot into cm, backup and flash a different rom and see if it will charge
i had to do that with a droid x i bought off ebay, someone had flashed a version of miui that had a bug which caused it to think the battery was always full and wouldnt allow the phone to charge

Amps is a measurement of current.
Voltage is a measure of the charge and 3.65 volts is still a good amount. The nominal voltage for the battery is likely to be 3.2v and you're nowhere near that. For example if it took about 3 hours to run the battery down from 4.2v (full charge) to 3.65v then you should be able to run the device for maybe a couple more hours before the battery is close to being drained.
[just a guess here]
The firmware does battery management. Shuts off the device when it thinks the battery is about drained and stops charging when it thinks the battery is at about full capacity. The software is probably out of sync with the physical state of the battery (calibration) and thinks the battery is at zero when it actually has plenty left. Or it has a bug. If you can't find an easy way to wipe/reset the calibration data then I'd go with the advice above and re-flash or flash something else.

Thanks for the quick response, I think your guess was pretty accurate. An hour ago I cleared the battery stats in CWM, and after a few more battery pulls and reboots at the Samsung logo I left it alone while plugged into the AC charger. Came back 45 minutes later to a warm handset with a black screen and after holding the power button down for a good 15-20 seconds I booted normally into CM with a 12 percent charge.
Because I was able to get into CWM and download mode just fine (and run off battery for a few minutes), I was starting to think I broke CM. Glad I didn't get punchy and reflash.
And yes, you're right about amps, I was implying amp-hours with the wrong term.
Hello,
I have bought an replacement OnePlus battery (the red ones) it looked identical to original one, the only difference was that it had an extra sticker hologram like. The battery was replaced at a service center (after I have ordered it my self, it also comes with 1year warranty).
The issue started the first time I changed the battery. It came charged at first to 55%, I used it until like 35% and then I left it to charge. Charging stopped at 90%. Accubattey measures a capacity of 3050 mah. However the voltage was at 4.280V and at this point it will not accept any more current (charging current drops to 0mA).
When normally charging it with the original charger it draws the usual 2 ~ 2.1 amps. Then I drained it to 0. Now it charges to 95~97%.
My questions are. Is the voltage correct for stopping the charging ? Should it not go 4.35V?
Do you think that repeted discharge to 0 cycles my fix this issue?
Should I consider using my warranty, for the battery and request a new one? Also on this topic. On the supplyer site it states that 5 cycles should be performed to calibrate the battery.
Did anyone else experienced this?
Thanks
calibrate your battery and see if you could find any change,if not, which rom/kernel are you on?
Well I am running 25 Dec CM 13 by sultan XDA, I did not flash a new ROM after the battery replacement.
What steps would you suggest for calibrating my battery ?
I was thinking of dischargeing it to 0 then trying to start it until I get no response from the device. I mean not even show the boot screen. Then leaving it like this for two hours. And then retry to start it, just to make sure the battery is all the way discharged. Then plug it in and leave it to charge over night and see what happens. And if it's still not 100 repeat until it happens.
Thanks for the reply.
