I've been slowly draining my G1 since yesterday, with wifi on and auto-check email every 10 minutes. It lasted almost 24hrs before 2%.
I noticed it slowly went to 2% around 12pm today and at around 5:30pm, it finally shutdown. That's almost 6 hours using the last 2% of battery. I did check battery status a few times and also checked websites/market for a few minutes during the last 2%.
Is this odd? Should I wipe my battery stats? It doesn't seem calibrated to me.
Does it happen often that it hangs at 2%, if so wipe the stats and drain and shut off and recharge. Could just be the new battery breaking in.

When you wipe stats you should let the battery die out then fully charge to 100. You should be happy you get so much time out of 2% though
Actually this has happened to me, it seems that once the phone enters the 5% range, it lasts just as long as everything else put together.
i wish i were that lucky to claim any of these things. My phone under very very moderate usage lasts about 2-3 hours from fully charged. It has been like this for a while and the ROM i'm running now is just making it worse. if i dont touch and send a couple texts messages it'll last up to 4 hours but that's it. I'm going to reset the stats and see if that corrects it before i go and buy a new battery.

Which is weird because using the stock battery I can get 12+ hours with moderate usage, this includes browser and wireless tethering.
I've been recharging it for a few hours now. The phone is off. It'll charge for another 10 hours before I turn it on.
Should I have wiped battery stats before I started charging? Or can I just wipe it before I boot up Android?

I guess wiping them at full power wont hurt, but then you must then let it fully die again and recharge it fully.
I just unplugged it from the charger. Booted into recovery, wiped battery stats, then rebooted. It now says it's at 87%. Somehow it took 13% to do those 2 things.
Hrmm, your battery life shouldn't be that bad, custom rom or not. Did you overcharge your battery? That seems to be a common cause for poor battery life.

How do you overcharge it? Shouldn't it stop when it think it's full?
This morning I used 'battery info' in the settings area and it only said the voltage was 4.05v or something and at 91%. This was for at least 9hrs with phone off and using HTC usb charger. I plugged it back in, while the phone was on, and it charged to 'full' in 10 minutes.
I'm recharging with phone on now tonight. I'm also currently using my motorola razr usb charger. It seems to charge faster than the HTC usb charger. It's voltage is now 4.15v and 61% now.

How do you overcharge a battery? If you mean leaving it plugged in long after it's fully charged, that is such a common thing to do it seems like lots of people would have battery problems. Almost everyone I know plugs their phone in before bed, and unplugs it in the morning. Most phones are fully charged in under 4 hours, so that leaves roughly 4-5 hours of being plugged while already fully charged every single day.
Well I'm basing that claim off of a t-mobile rep (hahah reliable isnt it?) who told me that overcharging the battery, or keeping it plugged for the majority of the day (which is what i tended to do) could harm the battery, causing it to give off false percentages or making it unable to hold a charge.
And also, from personal experience, my battery did begin to bulge outwards, and would not hold a charge for more than 4 hours. So I just assumed it was because I had a tendency to plug my g1 in when it wasn't necessary, and keep it charging. So perhaps my previous claim wasn't so well supported. I just based it off of my experience and what the reps told me.

lol haha that sucks
since i download a font pack, keyboard skin and better keyboard once my battery hits 10% it usually dies within 5-7 minutes if i have swift running in the background
but before the most recent updates my battery would last about a hour or more with just swift updating in the background and the music player on pause
My X2's battery seems charging in eternity. Have it plugged almost half a day and still is charging. I'm always turning my X2 off when I'm going to charge it, so I can see the battery icon when it's full. But this one's crazy, when I turn on my phone and looked at how many percent that it has been charged...it says 100%. But then again when I turned it off (still plugged to a charger)...it's still is charging.

Same issue as mine. I wonder what's causing this?
dont worry
this is the problem that many of us are facing with.
no way to get rid of. phone jast charges till 100%, and illumination stops , but the status remains charging. but really its stopped. the charger and battery both get cool.
Had anyone of you did try to send it to SE service center to address this issue?
Many times when I charge the phone the % indicater will just stay at whatever it was when I plugged in the charger. If unplugg the charger for a few seconds and reconnect it again the % indicater will update.
It's just one of those bugs.....
l have contact SE about a month ago..still no reply

It's better to leave the phone on when charging, that way the OS itself can control power management.
Really though, don't worry about it... as it has been said... it's just one of those things

Thank you for that info. But, how long does your battery lasts? Mine wouldn't even last 24 hours.

This is a question that is very difficult to answer as it depends on which applications you are running and how you use your phone.
Earlier this week I experienced that the battery dropped from 100% in the morning to less than 20% around 5 PM after having used the phone quite frequently throughout the day.
Yesterday I used the phone very little and from 100% battery yesterday morning I'm now down to 59% after 26 hours of use.
If you want your battery to last make sure you:
- turn off the screen when you do not use the phone
- turn off WiFi and Bluetooth
- don't use the radio
- turn of GPS
Maby someone else have more tips on how to get the battery to last.
here issue is not standby of battery-it is simple charging time and unacceptability of x2 to stop charging procedure. it just go on and on with charging(it does not display when it the battery is full it display that it is still charging-even if the phone is on charger more then 10h!!)

Sometimes I can use it all day and still have somewhere around 40% to 60% left at the end of the day. If I don't use it that much, it will maybe drop 10% per day. I have gone 3 days once without needing to swap my battery.
I have a standalone charger and 3 batteries. So I swap out the batteries from there every time it is low. It could be possible that the standalone charger does a better job of charging to full capacity.
EDIT: I also leave my 3G on always!
My battery lasts 3 days,about 30min of talk every day,5-10sms,20-30min of wifi,3g is off,gps not using yet...so that is about that.

3 days? And mine was just about....damn!
I have had my S2 for about 4 weeks now. The internet at home conked out so I have been using the the wifi sharing feature on the phone a lot - like 4-5 hours each day for the last ten days, and since this feature eats up battery real phast, its been sitting on the charger for most of that time, and then some more.
Now since the last two days, the phone doesnt charge anymore. In fact it drains battery whilst connected to the charger. The battery lasts about 2-3 hours now with moderate usage. I managed to get it to full charge when it was switched off and charged overnight for 6 hours. I've attached the results after that full charge
This is after the phone was plugged in for about 20 minutes. If you notice on the right side, the battery is draining while its plugged in!!!! The big drop was reading and sending a few emails, reading some news etc.
I installed some battery monitor apps from the market and they showed the battery being in good health. Any suggestions ?
Try recalibirating it..
let it run down completely and full charge ( don't use when charging) then use until almost dead again ( don not use charger in between) and full charge again.
Seee if that helps or go get a new battery :/
So after a bit more testing, I notice the phone charges at a normal rate when its switched of.
However when its running, then it doesn't charge at all, and over time drains battery, but does drain slower that it would if its not charging.
So one of two options
a) Battery's charge capacity is severely depleted, and is not able to hold much charge. However this battery is less than 4 weeks old~
b) There is something that is absolutely devouring the battery. (screen is what shows up us having used 60% of the battery)
If its battery, will it be covered under warranty? If its something else, how do i fix it. I'm still on 2.3.3 but this seems a bit extreme for the AOS or WIFI bug.

So thats pretty much what ended up happening, it died completely, had to charge it overnight to full charge...and still only lasted a couple of hours.
My guess is that the constant load on the battery running a hotspot has hooped it. Might get warranty support if you don't disclose how you were "abusing" the battery.
Cheap temporary solution is to buy a set of cheap knockoff batteries from Ebay, less cheap is to spring for a genuine Samsung unit. Long term solution is to get your home internet working again.
First step would be to backup all data and factory reset .
That fails i would return under warranty .

Just an update - I removed all the widgets from the home screens and its actually charging now I had the AP widget, the stock price, accuweather, a few widgetdroids, flashlight, photo frame, espn news, touchdown calendar and pulse.
Its not even a month old... and runs pretty damn hot as it is, I dont want to take a chance by using a cheap battery. If i have to, I'll buy an original.
But as far as abusing the battery - its should not be any different than running your laptop plugged into the charger at all times right - how is that beyond normal usage?
After it charges up fully, lets see how long the battery lasts in this 'lite' mode.
Just an update. I'm not sure if was the recalibration suggested by tfn, or removing all the widgets, but i went from losing full charge in 2 hours to losing charge at a rate of 2% per hour under heavy usage!
This is crazy - i think those widgets are taking up way more battery than we think.
Hi guys,
Does anyone have any idea to this WEIRD issue I've had with my Desire Z?
Basically, my phone was working normally last night. I then put my phone on to charge as normal before I went to bed, and I left it on the bed. About 5-6 hours later (I had to get up early today...) I turned over and touched the back of the phone and woke up shocked, as the back of the phone BURNED me! I got very confused and looked at the phone. It was VERY hot to hold, and it was on 42% battery. I then took the battery out, and it was almost hot enough to burn me. I left the battery out of the phone until I got up properly and tried turning it back on, and it got very hot, very fast.
I figured it could be a problem with the 1800 mAh Mugen battery I was using, so I decided to put my old stock HTC battery in. I got the same problem.
It seems to have got slightly better now, but I can only really use the phone in 5-10 minute bursts now. When the phone has booted up the battery will report around 36 degrees. After 5-10 minutes it sails up to about 50 degrees before I turn it off. The battery also drops off fast between reboots, losing around 10% each time I reboot (however, it doesn't seem to drop that fast when I'm actually using the phone...).
I am rooted and using Cyanogen Mod 7, and I recently flashed to the 151 nightly. I tried flashing to some of the earlier nightlies I still had on the phone, but the issue is exactly the same.
I did have the phone in the bootloader for a while (volume down+trackball), and it didn't seem to overheat. However, when I tried charging the phone with the device off the battery seemed to get VERY hot (way more hot than normal).
Luckily I can still back up anything I need to back up, and I am going to start doing wipes soon (assuming the phone doesn't overheat while wiping, which worries me!), but I am very confused!
I'm thinking that some sort of short circuit has happened, or something?
Does anyone have any ideas? If it's a definite hardware problem I can get a replacement fairly easily, but I do love my Z, so it's the last thing I want to do...
Very lucky my dad has a Samsung Galaxy Tab I can borrow as a phone for now. It will be fun for a day or two having a 7" tablet as a phone, but it will get old fast!
Thanks a lot, all!
Edit: I think it's had it. I tried using another charger and another USB cable and leaving it charge for a bit. When I came back after about 15 mins, again the phone was very hot, and the indicator light was flashing green and orange. When I tried to boot the phone it was dead. When I plugged it back in the indicator light would flash orange on and off for a while, then start blinking weirdly. Lucky my mugen battery still has about 15% charge... xD

It's *possibly* this problem.
My phone does the same thing, gets SUPER hot when charging, and has extremely short battery life.
Mine's not charging at all now, so I'm not even sure what to do at all :/
If I use the phone a lil and my Mugen battery dies, I won't be able to turn it on at all, so I'm not sure whether to start wiping and stuff now...
General consensus is to not leave the phone to charge overnight?
not with today's technology. all batteries (atleast good ones) have an internal circuit that keeps the battery from over charging. it also provides a method to maintain the charge by letting the phone drain some battery over the night by 5-10% then performing a trickle charge to slowly (very slowly) recharge the battery.
I've been leaving my stuff charging overnight for over a decade. It's not as bad as you think it is.
Apparently I am in the minority, but my VZW LG G2 (Stock) was affected the the slow charging battery drain issue after upgrading to Lollipop.
It's crazy just how slowly the phone would charge and drain. After the update my phone was constantly attached to a charger. It couldn't make it to mid-day even with little use. It would take hours to gain just 20-30% charge.
After months of complaining I finally "downgraded" to KitKat. The difference is amazing. I can easily make it through a full day with moderate use and I can almost fully charge the phone after about an hour. It's great.
Has anyone had this problem and figured out a cause or solution? I've always been stock, but has a custom lollipop ROM worked better? At the moment I think I'm going to wait until there's another update (hopefully) before upgrading.
I am having same problem as yours, the battery problems are on the rise with Lollipop update. Sometimes I wish I shouldnt have upgraded. But anyhow, I solved my problem by using a good charger, more details you can read on this page: http://www.techkhoji.com/slow-battery-charge-android-iphone-samsung/
Argh! After weeks of deferring the daily lollipop update request I was half asleep on morning and accidentally started the update. I couldn't stop it once it started.
My phone was just about dead when the update finished and I let it fully charge. To my surprise it charged surprisingly fast. After it was fully charged (and unplugged) the phone stayed at 100% for about 20 minutes of continuous use before it dropped to 99%. I was again surprised that the phone held a charge (no charging) all day with moderate use. In the evening it stayed at 0% for a while before it finally died. I suspect the phone was calibrating the battery during this initial use.
I thought perhaps the problem was solved, but a day later, the phone is back to charging painfully slow.
I actually measured the charging current, it's not just my imagination! I have a USB Meter and when the phone was on kikkat and for the first day on lollipop it would consistently charge between 1.5A and 1.8A. Now, it will only charge at 0.46A. I'm using the same chargers and charging cables.
What could have changed? Is there a way to reset whatever battery calibration may have occurred?
