Hey Guys,
in the last few days I noticed following strange battery issues:
When I go to bed in the evening I plug my phone to the charger,
in the Morning I have a green LED and battery is at 100%.
A few minutes later the Battery has a massive Drop from 100%
(From 100% to 58% or 100% to 38% or 100% to 61%)
After I noticed this, I installed Current Widget to log the battery
consumption.
Here is what the Log says:
2011/06/22 02:16:15,64mA,99%,4.205V
2011/06/22 02:18:20,56mA,99%,4.205V
2011/06/22 02:19:39,54mA,99%,4.205V
2011/06/22 02:22:00,50mA,100%,4.205V
2011/06/22 02:23:00,48mA,100%,4.205V
2011/06/22 02:26:04,-104mA,100%,4.175V
2011/06/22 02:28:12,-104mA,100%,4.175V
.
.
.
.
2011/06/22 08:24:33,-48mA,100%,3.874V
2011/06/22 08:25:34,-78mA,100%,3.874V
2011/06/22 08:26:34,-46mA,61%,3.869V
2011/06/22 08:27:34,-154mA,61%,3.869V
Two whole Logs can be seen here: http://pastebin.com/yfzBcJk3
So my question is:
Why is the battery depleting between 02:26:12 an 08:24:33
while still plugged in?
Is this a Bug?
How can i fix it?
At the moment im running my IncS on Android Revolution HD 1.0.2 ROM
(I have noticed this also with 1.0.1 and Unitiy Kernel...)
It's not a good idea to leave the phone pluged to the charger. When its fully charged i always take the charger out.
There is several threads about that, e.g. this one.
same here m8
but i found, that cause is Current Widget. Uninstall it and everything gonna be ok. if not - install Power Tutor and find the way your power disappearing.
i have around 1% battery drop every 2 hours and 30-40% with Current Widget installed. (on stock and Android Revolution HD ROMs)

Erm ... when I am asleep I wont plug out my Phone, because, well I am sleeping
Well if you read through this section, you will see a couple of threads with this discussed.
The issue you are facing is common.
Once the phone is completely charged to 100%, the phone automatically stops drawing power from the charger.
So lets say you start charging your phone at 2:15, it may charge up fully by 3:15.
Though it is still connected to the charger, the phone stops charging once it reaches 100%.
Then the phone starts drawing power for its normal usage, standby, display, any apps running in the background etc.
So by the time you wake up at 8:15 (or wenever) the phone wen connected will still show 100%, but after unplugging in a couple of minutes, it will drop down to the actual battery percentage.
nothing wrong with the phone.
i noticed the same with my earlier x10 after the 2.1 update as well.

Nice explanation! Always wondered what was going on here. So key is not to charge it over night?

well, key is to charge it as long as required.
Once it reaches 100%, any additional charging is a waste of electricity

Good point! Do you know if the phone's alarm still works when the phone is off? This was the case for my old i8910 hd and was quite handy for saving battery at night
UPDATE: No it doesn't!
Can somebody please tell me what is wrong with my battery? During usage it drops very fast but then when the phone is idle, it goes back up without charging!
And also when sometimes I restart my phone it drops by around 50-80% as seen in the screenshots!
P.S. I should mention that my phone is not rooted and running on stock 2.3.3
i had the same problem i upgraded to slim ics 3.5 now problem is gone and use battery calibration too . BTW which modem do you use i m from india too and my battery life is not good
I'm on ddjv9 stock modem and rom! Actually I have 1650 mah battery. It used to give a gud battery backup but lately strange things have started happening!
How long does ur phone last?
don't know yar i get around 5-6 hour video playback on full charge and facebook and browser last for only 2 hour and music around 7-8 hour N on a normal usage i get around a day :| don't know its normal or not n screen brightness on auto and i use only 2g
I used to get around 8-9 hours of video playback and about 2 days on normal usage! But the brightness used to be around 10%!! 2 hours of browsing is less, even on auto brightness!

Have you tried "bump charging"?
1) Power up (if not already) and plug your device into a power source.
2) Wait until your phone indicates it is fully charged.
3) Unplug, press and hold the power button, and select the option to power off.
4) Once powered down reconnect power source.
5) The display will show a battery charging, wait til it says 100%
6) Once it's fully charged(100%), unplug the device and quickly reconect again
Repeat steps 5-6 process (approximately 3-4 times)
this is called "bump charging" and its the same principle for all android phones

Yes I've tried bump charging also. It works fine for that cycle but the next time I charge it normally, it goes back to being wierd!
The problem is also that when I turn on my phone after full charge, it shows less than 15% battery and then rises slowly itself- as seen in some screenshots!!
I remember have selected an option so the battery wouldn't necessarily shut off at 0%. Now my phone shuts off at approximately 4%. Anyone remember where this option is?

I recently noticed this as well and would be interested if there's a way to fix this.
It has happened to me, too. Yesterday my phone shut down at 25% and 14%, but after turning it on again I could use it normally.
I'm, obviously, also interested if there's a solution for this.
Mine has done the same thing a couple of times. It's only ever happened once the battery is less than 10% but it's still annoying. I also had one random reboot today but that was the only time that this has happened.
I could swear I had selected an option for this...but I can't find it anywhere. Does anyone recall having seen this??

I had some weirdness with this myself yesterday (my 2nd day on the phone).. I was literally laying in bed before going to sleep, marveling at my battery life after a day of heavy use (18 hours and 39% to go, SOT 3 hours) and it just shut off. I tried to turn it back on, but got the boot loader's big fat 0% screen. So I plugged into the turbo charger, and then it said 100% within a minute, I turned it back on, and then it was 85%.. Just decided to go to bed, left it plugged in all night. Took it off the charger this morning at 100%.. then over the next 2 hours it fell down to 55%. Figured the battery just needed to settle in for a couple of days. I've had it on a USB port for about 90 minutes now, and it's back to 100%. I'm going to take it off an constantly keep it between 80-100% all day. Hopefully it just needs to settle in and get some battery stats under it's belt? I've not seen this with many, or any phones before. Would suck to be out somewhere thinking I can make it to the next morning no problem, and then have my phone die 5 minutes later and I don't have a charger.
Has anyone found a solution for this issue?
i am with the same "4%" issue
It probably does that so it can already have a headstart for the turbo charging feature.
Have you guys tried re-calibrating the battery? I've experienced versions of what you describe, and here's how I fixed it on mine;
1 - plug into the turbo charger that came with it
2 - press and hold power button till unit shuts off, continue holding,
3 - continue holding till you see a battery icon on the screen, let go of the power button
4 - phone will vibrate, and a couple seconds later, the battery icon will show a % number, that is the correct level of charge in the battery, it is now re-calibrated!
5 - press and hold power button till phone starts to boot, you should be good..
From what I've read, this "out of sync" battery calibration is caused by using certain chargers other than the stock one. I saw it happen from plugging into a laptop usb3 port and an old blackberry wall wart (don't judge me). Other people have reported it from using wireless charging (I wireless charge every night without issue).
Hope this helps, good luck!
I just got the OTA update from KitKat to Lollipop (5.0.2) yesterday and I've noticed terrible battery life and very slow charging since then. My phone is always in its charger overnight and when I remove it from the charger in the morning it usually easily lasts until I put it in the charger at night again. During the daytime I do a lot of stuff on it (whatching youtube videos, listen to internet radio, whatsapp, internet browsing, making phonecalls etc).
This morning I removed it from the charger and hardly didn't do anything on it for the first two hours. When I wanted to send a whatsapp, I noticed battery had already fallen to 70% in only 4 hours or so - 4 hours of doing nothing while the phone was in energy savings mode! Half way through the day, with only some whatsapping, battery had fallen to 20%. When I connected it to the charger, it instantly dropped to 8%. After about an hour of charging, it was at 17% and said it would last another 6 hours before the phone would be fully charged. Usually I charge my phone in 1.5 - 2 hours!
When I did the update, I didn't do a factory reset and I would like to only do that as a last resort.
If I look at te battery statistics, I don't see any app using an obscene amount of battery life - the highest being Google Play services with 15%. But what I do notice is that "Cell standby" is responsible for 29% of the battery drainage.
Before I do a factory reset, anyone any tips?

This is directly from HTC tech support. To recalibrate battery and HTC charger when battery rapidly or erratically discharges, this procedure clears all battery stats, coordinates and normalizes charging.
Turn off Fast Boot in settings. Power off phone.
Plug phone into HTC wall charger and charge for two minutes or more
While charging, hold down volume up+volume down+power button and continue holding
Phone will turn on and off repeatedly every 15 seconds or so while continuing to hold all three buttons
Keep this going for 2 minutes, then release buttons WHEN THE PHONE IS ON
Now, let phone charge fully normally (with phone either on or off--doesn't matter) and battery level reporting, charging and battery life should be normalized.
Do this every month or so to keep power system healthy--even if everything seems fine. Also, don't leave phone on charger overnight for best long term battery life (according to HTC tech support: "The first thing they tell us." This is true even though charging is supposed to turn off when battery is at 100%)
Battery recalibration ... Many techs say it's a placebo. But, I will follow this manual, just in case.
I do confirm, though, that with L 5.0.2 charging takes longer, phone drains faster with the same as before apps and usage, phone is often hot, and I've started to get regular 'can't charge, your phone uses more power than available from charger'.
Re phone uses more power than available, it happens with all three original HTC chargers I have, so I have to use the charger from an Asus tablet (1.5A output).
I haven't done the recalibration thing but I did some measurements and I now know why it's charging so slowly, just not what is causing it. The phone isn't switching to high charging mode and keeps charging at around 400mA. This means that when using the phone, it's draining faster than it can charge. I also think it's not switching to standby mode causing the high drain. Often the phone gets hot when it's in my pocket (when it is supposed to be in standby mode) meaning something is still draining the battery fast.
I will do the calibration thing and see if that helps.
I just did the reset thing (holding power + vol up + vol down) for two minutes. It's now charging but I can see it's still not charging in high mode. It's still charging at only 400mA.
Edit: Phone says it wil take 10 hours to charge (it's at 30% now).
Annoying, I know, but I'd factory reset the phone just to make sure the update has 'taken' correctly

Sounds logical. How did you find it out? Instrumental, or through a phone menu?
I have checked Setings/Power. Mine says Charging on AC, which supposedly means high charging mode.
PS. Again, whatever it might mean, when I get a 'phone uses more power than..' error, I connect the phone to a 1.5A charger (compared to original HTC 1.0A) and it solves the problem. I'm not happy with this solution, though.

There are a few ways I can measure this. I have a "Charger Doctor", one of those inline USB voltage/current meters and I have an "Energy Meter" which measures wattage going out of a 110/220V socket. Both confirm each others measurements. The Charger Doctor says my phone is being charged at 5.1V at 0.4A, and the energy meter says the charger consumes about 2.5W which is about right (the charger looses some energy through heat and the Charger Doctor consumes a bit of energy as well).
But...
To be sure, I tested a few different (but identical) chargers and changing the charger made no difference. But - and here comes the strange part - I tested about 20 different USB cables and with only two my phone charged at 1.0A (which I assume is the M7's max charging current). With all the others it charged with 0.3A-0.5A. Only with those two cables it charges in high charging mode. So apparently something changed in the charger detection. Before the update I was able to charge the phone in high charging mode with other cables as well.
Also, it seems like it's now discharging not as fast as before, but I will be sure tomorrow after it has fully charged and after I've used it all day.
Edit: Yep, charging is at it's normal speed now. It's at 60% and the phone says it will be 1 hour and 1 minute until it's fully charged.
Edit2: Of the two cables it charges at 1.0A with, one is the original charger cable that came with the HTC, and the other is a cable that came with a Duracell Power Bank.
Well, after the three finger calibration, charging seems faster, and I think battery holds longer (or maybe I want to think it does, because still not sure).
One additional observation is in about 20% cases my phone is stuck during boot until I connect or disconnect the charger for a second. By connecting or disconnecting the charger, something triggers the power state and the phone boots normally.
So yes, you may be right about new power management in Android 5.
(I'm now on IC7.0.0 + ElementalX 20.0, HTC M7 Int'l))
Well, even though charging times seem normal now, it is slightly erratic. I can see the percentage making jumps up and sometimes down while charging.
Also, battery life still is very poor. Battery now lasts until halfway through the day while before it would easily last all day...
Is there a way to revert to KitKat? Other than a lot of annoyances I haven't noticed a single advantage using Lollipop.

Factory reset
I had terrible battery problems after T-Mobile upgraded my HTC One (M7) to Lollipop. The phone was constantly awake and churning with the GPS probing for a signal every few seconds. I'd lose 50% of my battery in a couple of hours. I went through the battery recalibration suggested by HTC support, but it didn't work well. Finally I did the factory reset. It worked perfectly! Now my battery life is better than ever and the phone will go well over 24 hours on a single charge with normal usage. Recovering from the factory reset was easier than I anticipated. Google Play Store remembered and reloaded all my apps automatically. The only headache was having to log in to everything again. Well worth the effort.
I did a factory reset as well and it looks like it has improved battery life. I'm still on my first day after the reset so I won't be able to really tell after I've used it for a couple of days. But like I said, the hard reset seems to have made a difference.
It has been 15 hours now since I unplugged the phone from the charger and it still has 43% left. But I just noticed a few minutes ago that two energy settings were set different than before the hard reset. Screen brightness was set to auto (when before I had set it to it's first dim setting), and data connection was set to switch off after a long period of inactivity. (while before it was set to always on). I've changed those settings and see if that makes a (big) difference.

I have Wifi always on.
Tested it for another day and battery life has definitely improved quite a bit but it's still nowhere near what it used to be with KitKat.

when i woke up this morning my m7 was 100% it's now 11;10 and it,s now 70%
I'm getting exactly the same problem.
HTC support said they never heard about such a problem and their conclusion is to send the phone to be repaired
I don't know how to rollback to previous version and it doesn't looks like to be a new fixed version on the way.
Or at list I haven't heard about it.
I also noticed it doesn't make much of a difference if I turn on energy savings mode.
With KitKat, my phone would easily last the whole day without energy savings mode. Now with lollipop I have to hook it up to a charger in the evening - even with energy savings mode enabled.
The thing that sucks the most is that my phone drains in alarming rate when playing a game, or listening to online radio or watching youtube videos. 30 minutes and battery drops from 100% to 50%. And the phone gets really, really hot. Before lollipop, it would drain perhaps from 100% to 85% and the phone would not heat up at all.
There are so many annoying bugs/features with lollipop, I'm considering an iPhone for the very first time ever as my next phone. Mind you, I've never been a fan of Apple stuff. But Android is just getting ridiculously bloated and simply doesn't work very well anymore. It looks like every update makes my phone less usable. And I hate the fact Google thinks it's perfectly fine to disable/remove stuff that people have come to depend on. Like my notes (amongst man other things). Google in all its wisdom has removed the Notes app making all my notes inaccessible. The only way to get my notes back is to install some third party app from the Play Store and have it transfer my notes to the cloud. First of all, I don't want a third party app handling my notes. And I most certainly don't want my notes stored in the cloud. I travel quite a bit and I don't have internet access everywhere I go, making my notes inaccessible again.
I charged my battery. Took it off the charger and turned off the screen. When I woke up the phone was off and I dead. I am on cm12.1 fairly recent update. I updated a couple days ago. I just want to know if anyone else had this issue?
Only time thats ever happened to me is when I was camping in the woods. Like it was searching for a signal all night and killed the battery.
I had something similar happen to me over the weekend. I mostly use a Choetech Qi charger, and pulled it off the charger Saturday morning before heading out for a day of motorcycle riding. After the ride...~6hrs later my phone still showed 100% battery. As I was catching up on emails etc..the phone just shut itself down. I rebooted...then it shut down again within 30 secs of use.
While it was still off, a quick press on the power button popped up a battery image showing 0% battery. Within 2 seconds of plugging in a charger...it jumped to 100% again. But the phone would not stay on, unplugged at all. I tried wiping the cache hoping that would clear out the battery monitor, but not luck there. The only that worked was turning the phone off, plugging in the OEM Turbo Charger, and letting it charge over night.
Do you have any app monitoring battery usage like betterbatterystats or gsm battery monitor?
sometime obviously kept your usage on while you slept. not normal. either searching for a signal all night, or a misbehaving app, etc. y
I do not have currently have any 3rd party monitoring app. But it's probably not a bad idea. I just think that something with the wireless charging eventually whacks out the battery calibration. As long as I can "reset" everything with a night on the Turbo charger, I can deal.

Radon,
I'm seeing nearly the same problem, but mine is at 80% not 100%. I tried doing a full charge on a standard (non-Turbo) charger overnight, and it changed things, but still not in an acceptable state. Did you try using a standard charger? Or did you only try the Turbo charger?
Verizon and Motorola are telling me I need to do a factory reset and/or get a new phone, but I'm trying to do my research first.
Clear the app cache (Go to Settings->Storage then click on Cached data and hit OK). Then reboot into recovery to wipe the cache there (note it'll take upwards to half and hour so don't freak out if it looks frozen). Then turn the phone off and leave it on the factory charger overnight (or for a while after it reads 100%) with the phone still off. This clears the cruft to fix misbehaving apps, then calibrates the phones understanding of what a full charge is. You also might want to delete any apps you no longer use, especially ad-ridden games, system hook apps like keyboards, and things that track location or status which might keep the phone awake.
After I shattered my screen on my last turbo and got a replacement I've been having issues with my battery. It would randomly die and wouldn't respond or let me turn it on without connecting to a charging cable. Sometimes it goes from a good charge to 39% and turns itself off but often, like I observed today, when I looked at my battery trend it actually went from 75% to 8% in an instant. Not sure what the cause is. Could the battery be discharging somehow??
