Has anyone else seen this? From 100 to 90% the power just drops almost instantaneously but after 90% its normal.
Already been brought up, a lot.
Apparently when your phone charges up it stops once it reaches ~100% and begins discharging, even though it is still on the charger. People will turn their phone off after a full charge and charge for an additional 20min to an hour before they get another green LED. People have reported much longer battery life when doing this, but it is a pain in the ass.

Ahh interesting. I thought I was running into an old winmo rom flashing issue where if you flashed under 50% battery life you could never charge the device above that point.
Yea it sucks but it works... I just ordered an external battery charger since I have 2 batteries now so I don't have to do this anymore

Hmm i tried and it acted the same way.
Apparently the HTC models act like older phones did back in the day. What HTC needs to do is put something on the phone face itself when new that says "CHARGE FOR 4 HOURS BEFORE INITIAL POWER ON FOR MAXIMUM BATTERY LIFE."
Once you do this once you dont have to keep doing it. I also powered on my phone the minute I got it and activated it without charging it first and I was seeing this issue until I did a power off charge. The phone runs from 6am to 11pm without an additional charge cycle in the day and that is a huge improvement for me. I was charging the phone twice to three times daily.
Hello does this method works for x10 to make battery last longer?
Hi *******, I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly.
I don't think that exact method will work.
It could just be me, but whenever I plug my phone into the charger when it is switched off, it switches on the phone, which doesn't really help when you're trying to charge with the power switched off.
Mine won't charge switched off either, always turns on.
I just run my battery flat a couple of times, seems to help alot.

Modern batteries are not supposed to run flat, from what i've been reading. They stay fresh if charged a little and often. I'm not saying anyones wrong, just what i've heard and read.

They don't go flat as you'd expect. Lithium has an operating bandwidth. Say 3.5 to 2.9 thats your battery indication from full charge to low battery. Technically the battery is never fully discharged. As someone posted above, a little and often with these new batteries wins the race.

I discovered the solution for X10 calibrate. My bat was showing 100% so i pulled ut the charger, turned the device of, took out the battery, put the charger in and finally putting the battery back. When phone was restarted my battery started charging from 88%. hope it works the same for all!
Edit: after led turning off and bat showing 100% i did the whole procedure again, and again it starts charging from 88%!

After nearly 1h since stop charging i'm still on 100% after a few texts, checking xda on tapatalk ofc and surfing a few webpages, i was down at 99% but magically it restored itself when leaving it be.

Gonna try this myself. I'll report back soon.
Edit-
Mine starts to load at 88% too.
Edit2-
When loading, my Battery Indicator states "overvoltage" and shows 4,21 volts. On my second X10 it's only 3,77 and it doesn't say overvoltage. But when I take it off from the charger the voltage drops to 4 volts and stays at 3,77 on my other X10. Bizarre.
Edit3-
Battery life seems to have improved a lot. With the screen at 100% brightness and the sound on on Gameboid I only lost 1% per 10mins or so. Quite an improvement from losing 3% per 5min.

thanks for the tip! my guess is that the x10 isnt fully charging the battery?
which is kinda werid because i am using my old X1 batt so it shouldn't be draining
this fast.

Nice to see there are actually improvements, i had to rush to my buss while still doing the third cycle so i dissconnected at 96% and it then kept ticking up to 100% on it's own. It sounds worrying though that you get an over voltage allert, maby we should not do this to much if it might damage the battery. But a few cycles just to max it out can't harm?! I belive the 88% -> 100% went faster though for each cycle so this might be a sign that the battery is pushing to the limit little by little. I'm gonna go for a few more cycles to see the results of it.

Yeah, well I had only done two cycles when I noticed the over voltage and stopped there. It seems fine at the moment, temps are normal etc.
I just did one "calibration" again and i actually played around so much with my phone today so when i got home it was on 10%, charged it to 100% and when doin the procedure it reset the battery gauge to 96% rather then the 88% i got earlier.. i wonder if it has any connection to my unplugging the phone at 96% this morning.... hmm, i just don't get this. hehe
Edit: second cycle now and i'm back to charging from 88%.
Thanks for all your constructive ideas. Im also worrying about the battery damage because this is not an official measure. I'll try a few cycles however.
Can you please advise if the coming 2.1 will bring X10 extended battery life?
tried the cycle, first cycle went down to 92%, didnt take long for 100%, second and third she rebooted at 100, sitting at 4.201volts stating overcharge. will update tomorro with a full days use.
I honestly can not tell if my battery has improved from this, but i'm a very inconsistent user

I haven't tried this calibration by taking out the battery when full and putting it back in thing yet, but I have gotten over voltage condition when recharging anyway. It occurs in the 90% and higher region.
Usually, my voltage reaches 4.21V at 100%.
I have very good battery life for a smartphone; I think mostly due to the R2BA020 update for Canada/Rogers. Also, I turn off APN connection most of the time. I did a couple full discharges early when I got the phone and don't know if that had an impact.

So this should meen that the battery is always charging at an overvoltage wich would also meen doing this cycle should not harm the battery more then normal.

Used this did it three times and after the third time on reboot battery on 100% see how long my battery lasts now
Edit-Worked great but then had troubles with ROM so had to reflash. Now when I try this phone just goes into flash mode when USB is plugged in even before the battery. Help?
Ok, I never did this before, but my phone was at 100% charge and I decided to turn it off and charge...... Well it took about 1 1/2 hours and the light finally turned green. So I took it off the charger and plugged it back in and now its been charging for over 2 hours and the light is still red!!
I wonder if this is why my phone was dying so fast. I cant believe that even though my phone said it was at 100% its been charging for over three hours OFF and its still going.
This is just crazy.
I found on the evo forum, can't remember the link, that our batteries have different cells. Charge your phone for up about 6 to 8 hours, while on, turn it off when fully charged, then unplug charger and plug charger back in when led goes off and charge until led turns green again. Repeat that process of unplugging charger until led goes off and plugging back in until green a total of 10 times. From what I read, it's supposed to help improve battery life. I haven't tried it myself so I can't verify it works.

I've also read bump charging like that can be seriously detrimental to battery health over time...besides this phone doesn't need it...just recalibrate the battery by letting it die until it won't turn on, then I like to pull the battery for 30 seconds to make sure it really resets but not sure its actually necessary....then charge it while off til the light turns green...I usually unplug before I turn it back on....I've gotten pretty stellar battery life with moderate use since doing that and rooting and removing bloat helps even more....like 25-35 hours (will be less if you use it heavily, tons of videos and games will kill it quicker, but even with reasonable amounts of games and vids you can hit 25 hrs for sure)....I've read doing this about once a month is good but letting it die too often is bad too

I tried that and for some reason while I was at school it would lose about 15% battery life while I was in class for about 1 1/2 hours with no use at all.
I use the tunein app while at work and I can start at %100 and after about 2 hrs it's down to %20
Ok, so its been like 10 hours the light turned green once I unplugged and plugged back in and the light stayed red for another two hours. I gave up and turned it on while it was red..... Battery was at 96%..... Wtf
Sent from my PG06100 using XDA App
when i charge my batt, i never charge it above 95%, and it actually last 2-3 hrs longer than a full charge.
Also if you notice, when u unplug it from a full charge, within the first 10-15min it goes down to 95-90%...
what im assuming is the phone over estimates its charge, and ends up over charging. then it has to let off the excess?? psh idk im only guessing based on observing

They design phone batteries these days so that you do not need to do these crazy tricks. In the past it was useful, but not anymore

Mine would do that too. Take a close look at your time without signal. I notice that I have horrible signal or that I am roaming when I'm in huge lecture halls. You use more battery life when your phone is contantly looking for signal.

My gf said her N7 showed a 0% charge even though 2 hours earlier she had a 60% charge. She then plugged it in and restarted, then it showed a 60% charge again.
Any ideas what may be wrong?

Not likely. Battery stats has absolutely nothing to do with reported charge level. Wiping it will have the same effect as clearing his market search history... None at all.

Are you using the charger that came with the Nexus 7? 'Cause the same thing happened to me last month. I used a charger I got from ebay, plugged it in, charged all day, came back, unplugged it, turned on & said it was in the red!
Same thing happened to me shortly after I had the N7.... and that was with using the supplied mains charger and cable.
All I did was leave it alone for a further hour and when I then went back to check the screen it had jumped all of 13%.
I was tempted to return the N7 but as it was night and I couldn't return it I left it on charge overnight...... The following morning it was 100% charged.
Since then it's been charged dozen's of times and not once been a problem since (says he touching wood).
My problem is that it wont show that its charging even tho it is. Tried all chargers i have and even the stock one is same. Was going to return it but all the horror stories I've heard i decided not going to bother. Chances are i get a worse unit back. Personally it looks like the connector is not going all the way in. I am going to shave some of the plastic off and see if that helps. Anyway I think Google needs better quality control at Asus and even at Samsung, i remember how my Gnex was packaged.

Hello,
I noticed some crazy things happening to my N4 during charging yesterday.
It was at about 20% and I had a few hours to charge it before going out for the night. I charged it to about 50% and then stepped out of the house.
After I came home at night, I plugged it in like I do before I go to bed. I woke up after 5-6 hours to use the bathroom and checked my phone. It was stuck at 76% charging. I knew something was wrong because it shouldn't of taken 5-6 hours to get to 76%. I opened my battery settings and noticed something very weird happening.
The indicator was saying "76% Charging" and then "76% Not Charging" and it was alternating between the 2 really fast. It was as if I was taking the plug out of the wall and putting it back in REALLY fast. I checked the outlet and it was fine, it was plugged in just fine (I've been using the same outlet fine for a week)
I restarted the phone and suddenly the battery jumped to 86%. WTF?
I kept it charging and went back to sleep. Woke up few hours later and it got stuck at 76% again! And it sat there bouncing back and forth like before.
I restarted the phone a FINAL time and then finally it fully charged to 100%.
WTF is going on?
Seems like your battery indicator might have been messing up, reboots fix this
Sent from my Nexus 4 using xda premium
Yeah sounds like it but really odd how it got stuck at 76%.
When it hit 86% it just stayed consistently charging but the % wasn't increasing. Looking at the battery graph from last night it seemed to be at 86% for at least a few hours.

I would leave it charging for such a period that it would be at 100% if it was at all normal.
Then reset battery stats, let it fully discharge through use, recharge, and see how it goes.

Reset battery stats without root permissions? Don't think it's possible, right?
