Since I've updated to froyo I can't fully charge my battery. Since I'm charging it over night, on the mornings I get random percentages, but always not 100% - sometimes 91%, 94%, 95%, etc. I saw other posts with such behavior, but I did not find the reason for this.
I've tried full discharge, as much as it is possible since on below 5-6% the phone automatically shuts down. I've tried on the morning unplug it, then plug it again after 5-10 minutes, but no gain.
PS. just to note that the battery life is a lot better with Froyo. Part of it is maybe because I do not have so much battery sucking apps like before, but still.

This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?
I'm not sure if this has been posted yet, but when I unplug my phone after charging it overnight, it gets to 90% or so in around 30 minutes without use, and goes down at a fast rate throughout the day. If I charge it and unplug it exactly when it hits 100%, I can use the phone fairly regularly and it will take around 2 hours to get down to 90%, and depletes from there very slowly. What's the reason for this, and is there any way I can get the same battery life when leaving the phone overnight?
Running CM7 with incredikernel, although my phone has been this way with countless ROMs and kernels.

Short answer: Yes, you will see better battery life, and no there is not really any foolproof way to make it work if you leave it on the charger after it hits 100%.
Long answer: The Incredible has a battery saver feature built in that prevents over charging by cutting off charge to the battery when it hits 100% (actually 96% according to the people who figured all this out and are way smarter than I am) and doesn't let it start to recharge until it hits 80%. The reason, when you take it off in the morning, it drops so fast is because it is no longer actually at 100%, but has dropped to a legitimate ~90% since having hit the "100%" threshold.
There are some kernels out there that do allow "trickle charging" meaning they keep the phone at a legit 100%, but I don't think many have seen much success using them with the Incredible.
I get around this by charging a bit at night (using anywhere between 80-100%), leaving it off the charger until morning (I usually drop only around 4-5% per 8 hour night) and plug it back in while I get ready and eat breakfast. This usually puts me around 95-100% depending how much I was able to charge the night before and seems to be a much more simple way to handle it than bump charging in my opinion.

I've seen similar topics regarding the quick drop from 100 to 90%, but the battery life as a whole seems to be much longer when it's taken off the charger immediately after it hits 100%. There's so many topics on here, I can't find exactly what I'm talking about, so it's difficult to judge. I'll definitely try the tip in the second post though. Thanks!
It will charge it up to 100% but it won't stay there if you keep it in. It'll let the phone die down to 90% then it'll keep it at that level.
So yes if you unplug it when it first hits 100% you will have a full 100% battery. If you let it sit for much longer than it'll be at 90%
It's been said that leaving it on charger for a while after fully charged messes with the battery meter.
I always bump charge. Charge it full while on then power off and charge till green lights on. Def gets me more batt life. Im getting 24+ hours on a single charge under normal usage with UD 3.1.1.

That should help you out!
Whenver i flash a new rom, i make it a point to use BatteryCaliberation from Market.
Though since the last couple of times, I have noticed a weird thing.
Whenever i let the battery charge, it stays on a particular % for too long,
in my case (most of the times), its 60% or 72%. And then directly jumps to 100%. (this 100% is confirmed by the mV in BatteryCaliberation.
And while discharging, it goes to 0%. Then when i remove the battery and power on, it shows 2% (Although one time , it went to 20% )
Is my battery broken and should i replace it? (It has been giving me crappy battery life too)
i've got this, always charges up to 70-80% and stays there for a while, then jumps to 100%, changing roms, calibrating battery doesn't fix it.
Always wondered why it happened, I assume it's to do with the battery but not sure if faulty or not, hopefully someone can shed a bit of light...
First guys The battery calibration has been shown to be pointless and useless. Dont bother doing it. Next if you ever do bring a battery to pure 0% then it will bot boot at all. The issue could be many things. From a bad battery to just the way your device charges. As long as it last a decent amount of time then you may be able to rule out the battery being bad. I wouldnt worry about it unless you see the battery discharging really really fast.
Try to go into recovery and wipe battery stats, and then discharge it to 0 % until it won't turn on and fully charge it 0 ma on current widget. it happened to me many times and this is how i fixed it (old problem on hd2 on android nand)
Guys I need your advise very badly regarding battery..I am using latest insertion ROM by siulmagic, whenever I am using my phone for surfing, using wi-fi, or watching videos, while charging, my battery percentage keeps decreasing, very slowly though, also if I put it on charge at 12 Am and when I see at morning at 8Am, it still indicating red led as it's charging, I thought my battery would be faulty, so I got new one, and charged it fully, it took 6 hours, when I turned on my mobile, it started with 99%, then decreased at 1% per minute, I don't even have sim in it, and network.is set to aeroplane mode, I replaced it again, and newer one is still the same..I have also flashed glite ROM, which is best in battery life, but with no help, to check the charger issue, I use stock g2 charger in my sensation, and it charged normally, please advise me..what's your opinion why my battery problems suddenly started? that it can't even charge whole night, previously when I don't have sensation, I used it for surfing, gaming, movies, and while charging, now when I turn on wi-fi or watch movies while charging, it decreases, and when leave it charging without using it..the percentage increases very very slowly especially between 90% to 100% it takes hours...
- try to reset battery stats... u can try battery calibration... only if u have root your phone...
- try to check which apps consume high battery...
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
