Anyone notice that when the phone is charging while off and reaches 100% - when you turn on the phone, the battery drops to 98%? From there, it can still accept a charge and then FINALLY indicate the battery is full?
I do have another battery coming from AT&T (because of overheating problems) but I am just curious as to what others are experiencing.
background info - this isn't my first Captivate and I have drained this battery a couple of times to "calibrate" it.
This will sound weird but it worked wonders for me.
*Fully charge the battery with the phone on
*Unplug charger and turn off the phone
*Plug in the charger and wait until its at 100
*Now unplug the charger and boot up the phone
C*Wait until its done booting up and power down the phone.
*Now charge the phone to 100 boot up and use normally

does it make any difference? like long lasting battery hours or so...?
the memory in the batter indicats full as i believe 90% and above or something.. it's normal :T .. but try to do what the previous poster said.. it's worked for some people
I did what he recommended and don't see an improvement in battery life. But, when I unplug in the morning it stays at 100%, it definately made a difference in that regard.
I did see a slight improvement when I cycled the battery a few times. Full charge to 100% dead.

if it's fairly new give it a week or two .. the battery should improve in a way.. if you're still truly dissatisfied then I guess get a new phone or buy a bigger battery .. I believe they'll have better batteries soon on ebay
I tried doing that charge/power cycle.. Once the phone was powered on it immediately dropped to 97%
This is the battery that overheats also..
Wish I could get my #2 captivate back.. I returned it because of the GPS problem - not knowing it was a global issue - I had the best battery life from that phone - 5 days of use easy on that one (without power cycling or anything) - The last 3 phones (all have been overheating) I'm lucky if I get 2 days out of them..
I keep saying phones because I was in my 30 day warranty, so every time I went in they did a complete exchange.. I am now out of my 30 day exchange.
Hey,
I just installed CyanogenMod 7 on my milestone using openrecovery. Everything was working perfectly, but the battery was draining like there's no tomorrow.
Started at 50% when I first booted, I downloaded a couple of apps from the Market, and went down to 20% (in the space of about 10 minutes). So I plugged in the phone charger (USB into back of my computer), and then while configuring settings, battery went to 4% (it was checking in 1% increments, which I have since found out that drains the battery). The phone then died. So, the phone was using WAAAAAY more power than the USB port could supply. Anyway, thought I'd let it charge for a while, then go back into the settings, and remove the 1% increments, to try and get normal battery life.
The phone recharges, and automatically reboots. Its still on 4%, but I went in, turned off the 1% increments. Phone dies again.
Charges about 10 minutes, reboots itself again. During this period, I did some research, and found that the battery draining can be caused by excessive CPU usage, resulting in the screen staying on even when it's off (?).
But, alas, no luck. I don't have enough battery to flash the stock SBF.
All I really want is:
a) a way to just have the thing charge without turning itself on, and
b) a workaround to get at least half-decent battery on CM.
Thanks,
David.

Try deleting your /data/system/batterystats.bin before trying this procedure out. You can use an app like Root Explorer to do this. If you're unable to, proceed with bump charging.
Try bump charging:
1. Remove battery, put it back in after a good 2-3 minutes and connect phone to a wall charger. Make sure the phone is still switched off while it's charging.
2. After it finishes charging completely (green LED), let the charger be switched on and connected - remove the battery alone (without switching off charging).
3. After a few seconds, you will see a "?" on your screen, after which you insert the battery back in (while charger is still switched on).
4. Wait till charging completes again (green LED).
5. Plug out charger, wait for 2-3 minutes and plug charger back in and start charging again. It should now be fully charged.
6. Turn phone on while charging, after booting into CM, try OC'ing it to 800MHz interactive governor, apply settings on boot and restart your phone.
Hope this fixes your problem. Good luck!
Anyone can feel free to correct me if I'm wrong.

I had the same problem some time ago and tried all this to no avail. I even changed to froyomod for some time, but CM7 is far superior so I just came back to it. The problem happened again this morning just after using google maps. I then rebooted and uninstalled all google maps updates. Seems to be working o far.
hey, yeah, just one problem with that - i can't boot into android for longer than about 3 seconds, and now there is no way to revert, as the bootloader says Battery Low.
Can't you boot into recovery, flash another rom and then reboot into android?
Don't charge from usb, use wall charger. That way, the system will boot only to charge-only screen, android system itself not running.
Hey, kabaldan, I found that out.
Charged 100% using the bump method instructed above. Battery life is still worse than useless, 50% in about a half hour.
will performing those other steps help?
Can you try another fully charged Milestone/Droid battery?
If that doesn't work it might be a problem with your phone's hardware. I know it might be a long shot, try cleaning your phone's and your battery's leads (connectors) if they might've accumulated rust/dust or something. Not sure.
Don't know if this is a similar problem but mine goes down in % pretty fast too but then it can stay for 1% for half a day
No, mine definitely dies. At around 5%, although I did turn off the 1% increments, because I heard they guzzled battery.
The battery life is getting progressively better, but as soon as I use 3G, or open any half-decent games, it drops to about 40% in ~.00001 seconds.
Although, to be fair, I didn't get great battery life on stock rom, either. And my ram always seem chokkas. Like usually only have about 50mb, and I'm not running anything too hectic.
Unfortunately, I think I'll get the Samsung Epic as soon as they bring out the GSM version. I just want an android phone with an unlocked bootloader, insanely large screen, and hardware keyboard, not to mention ~20 days battery life. Is that too much to ask?
How can I calibrate my unrooted phone
Sent from my Nexus 6 using XDA Free mobile app
You can't. Even if you are rooted.
Run your battery all the way down until it shuts off. Charge, uninterrupted, until fully charged. Voila! Battery calibrated.
Battery calibrating apps/techniques have been useless for quite some time.

My phone has gone through many charge and shutdown cycles and not even this has changed my 5% shutdown.
Have you tried leaving your phone plugged in after 100%? Let it trickle charge for an hour or two.
The battery 'calibration' stuff that people do is what android does automatically after getting to nearly full charge.
It hasn't been needed since gingerbread.
I have had this issue happen a few times, what I do is plug it in to turn it on , then try to run it down till 0 and then put it on charge while off till its 100% and leave it there for a few hours. Then after a few cycles, this occurs again. I dont charge in the middle, always charge at night until 100% and 30 minutes beyond that.
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.

lol :silly: you cant rule out that it wont work just because HTC decided to remove the software switch in the power options in its later updates, do the rest of it and skip that part, I dont have the option for fastboot either anymore.

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.
Hi all,
2 days ago I decided to calibrate battery, which is done by fully charging phone, then fully discharging phone with normal use. But phone turns off at 1% and doesn't fully discharge, so I turned it back on and stayed alive for 40mins at highest brightness watching videos on Facebook until finally turned off.
Then fully charge your phone while device is off, (but because device fully drained will be a bit tricky to charge it, don't know why, look like keeps 1% of charge to save charging settings or something) anyway, after a few attempts of plug in and un plug I managed to get it charging, and charged in full.
Result:
Better battery life, obviously. And the strange one is that refresh rate drop when unlocking device as stopped and device is smooth everytime, been over 2 days now without a single drop. Not sure how is this related but this happened with me, free to try it if you wish.
Thought to share my experience.
Happy to answer questions
How did you turned on? After i get the notification that in 30 seconds phone will shutdown, it does shutdown and when i keep pressed the power button its powering, showing mi logo then one logo with empty battery and shuts down again.
