Hi
The last few days I've been using my diamond, part way through a call the phone switches off. When I try and turn it on it'll vibrate then switch off again, as it does when the battery is flat. However, if I plug the charger in and turn it on the battery is reported as anything from 40% to 90% !! Just happened a few minutes about, before the call the battery was showing as 75%, 2 minutes later the phone died and wouldn't switch on. I plugged the charger in, switched on and the battery was at 92%. Occasionally, it will switch on without charging and the battery will show as 40% !
Anyone else seen this and got an idea of the problem ? The phone is 18 months and this is the original battery. Is the battery on it's way out or is there another issue ? I've hard reset the phone a couple of times but that's made no difference.
battery's are very analogue components and there is no good digital way to measure their charge
it's don by measuring the volt lvl as the more flat a batt goes the lower the volts will go
so you can't really trust it much as a batt at the end of it's lifespan could have normal volt lvls 1 min and be flat the next
The battery is dead then ? Though so, I've bought a new one, only 20GBP
Thanks for your response.
So I plug my phone in -- it charges to 100%
This usually occurs over night, however it occurs during the day when i charge it at work too.
AS SOON as I pull the plug out -- it drops from 100% to like 80% or 70% instantly.
In other words, it can charge to 100%, but it can't hold that charge, even while plugged in -- even while plugged in it will lose it's battery.
I have to quickly unplug it then plug it back in and let it charge up to 100% again (at which point it starts to drop, again)
Questions
1) why does this happen ? Is my battery done ?
2) how to fix this ?
You need to calibrate it probably, search for galaxy battery calibration
Or, you are having the Gingerbread bug if you are on 2.3... (See General sub-forum, there's the answer)
1) Because Lithium batteries can not be trickle charged without setting fire to your desk. Once the charging is done it stops charging till it reaches a certain level determined by the system. That is usually somewhere between 90-100%. Dropping to 70-80% seems like more of a software glitch than anything else.
Also don't unplug and plug it in again. This may be bad for your battery.
Also2 if you're plugged into the computer it seems as though the computer can't provide enough power from it's socket to run the phone with the screen on and in active use. Does it still do it on the wall charger?
had same problem
proper caliberation will work :]
Problem started yesterday,phone charge till 5% and than stop,it still says charging but its not.
try to get some battery apps to fix it and try a new cable...
Battery Fix
This is an issue with battery calibration (or so I assume).
What you will need to do is:
Leave the phone for at least 36 hours. Make sure that you keep the phone turned on for as long as possible.
Once you have left it for 36 hours, connect the charger and charge for a whole 10 hours.
Then, turn on the phone and it will possibly show that the battery is at 100%. If not, you need to install an app called CurrentWidget: Battery Monitor. It is available here: https://play.google.com/store/apps/details?id=com.manor.currentwidget
This app will tell you the voltage/current stored in the battery. If the mAh of the battery is 3000 mAh when left charging for 10 hours, then you will need to do this:
Fully charge the battery with the phone for 5 hours and when the phone is fully charged, unplug the charger and turn it off.
When your phone is off, plug it into the charger and let it charge to 100% again. The green LED light will indicate when this is done.
Next unplug the charger, turn on your phone and set the option to ensure that your screen doesn’t turn off, if you have this option. Then reconnect to the charger and wait for it to charge again to 100%.
Once loaded to 100%, unplug the charger again and do not load until the smartphone turns itself off after reaching a 0% battery level. Once off, fully charge it again and it should work properly. The screen setting can put back to normal again (meaning turn off after a certain amount of time).
Hope this helped!
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.
I do not understand why the percentage of the battery as soon as I turn on the phone after a full charge immediately indicates 98% and not 100%, even if the display shows off the full charge as soon as I remove the charger.
It's probably because your 100% battery level is nearing on 99% and every reboot, based on my experience, more often than not consumes 1%, maybe more, hence, 98% battery left.

I'd suggest varying how you charge the phone; 1) with the phone on 2) with the phone off
My (albeit anecdotal) experience is that when charged with the phone on, and left on the charger longer than when it says 100%, it's doing a 'trickle' charge, which then seems to charge it completely. Again, anecdotal, but it seems to me that after charging it numerous times with it on, then when I charge it turned off it seems to do a *full* charge.
ymmv
maybe I explained myself badly. in the evening I put the phone off and off. In the morning as soon as I accrue it, instead of marking 100%, it will score 98% .If it is when I unplug it from the charger and it is still off and it is 100% .
