Hi all, I posted in the battery life thread but didn't get any bites, so I thought I'd go up a level.
I have had two warranty replacement M8s which behave similarly. Both will occasionally not unlock with the power button, though the phone will still take a screenshot of the "unlit" screen by way of the Pwr/Vol- combination. Leaving it for a number of minutes will usually see it unlock normally. Is it conceivable that in-app misbehaviour could cause this? I would have thought that unlocking the screen is a higher priority event than a screenshot...
The second problem is that the phone shuts down at around 15% battery remaining (according to the display), but when plugged in to the genuine charger it is 0%. Oddly, whilst the phone is powered off between going flat and being put on charge then restarted, the battery manager reports that WiFi remained active. Furthermore, the phone continues to display "XX Hours on Battery" from the previous power cycle.
Screenshots should help:

I have apparently expired the number of express turnaround replacement handsets and am being told that I must return the handset for analysis. I'm pretty annoyed as I've already been inconvenienced, and am interested in getting an insight from members as to where they think the problem might lie.
I have recalibrated the battery a number of times, the battery test function finished at 90% and I only use the supplied charger.
Many thanks,
Steve

The phone shutting down at 15% doesn't seem that unusual. The % reported by OS is not a precise number. Its simply an estimate of battery remaining based on current voltage versus how you use your phone (or at least, how the phone thinks you will use it). Its an abstract number, and just what the manufacturers have come up with; since they probably decided that most folks aren't smart enough to understand battery voltage.
You shouldn't be running your battery down that low on a regular bases, anyway. Short, frequent charging is best for long-term battery life with Li ion batteries.
My phone shutoff at around 11% the other day (didn't realize my kid ran the battery down that low watching videos), and it really didn't strike me as that unusual.
The screen not turning on, on the other hand, is a more unusual. Possibly try RUU, if your version has one available.
Interesting... thanks for that Redpoint. I appreciate that running lithium ion batteries to dead flat isn't ideal for longevity, but my last two HTCs would happily go into single digit percentages. For example, my original M8 on Android 5 would go through displaying the red battery symbol, the hollow one and I think another one after that at 1% if I pushed it to. I also didn't elaborate, but actually using the current phone at around 20% battery will result in it clock down maybe 4% every subsequent 15 to 30 seconds. That's an excessively fast taper-off.
I'll look up what RUU means ?... I am a noob.
Cheers,
Steve
Just wanted to say that those three characters "RUU" helped a lot. I now have an option other than sending it back.
Much appreciated mate. ?

I got my Orbit today and charged it for around 4 hours. Since then it has been unplugged for at least 3 hours, during which time the battery meter has not decreased from 100%. All ROMs and whatnot are as they are out of the box. I have read it using SPB PocketPlus battery meter and the one in settings.
What can I do about this? Thanks.
have you been using the unit? I can charge mine up, leave it overnight (when it doesn't get used) and in the morning it's still 100 or 99%....
ther's nothing wrong with it unless you've been vigorously using it and the battery hasn't gone down.
This is because of the type of battery that is used
Normal battery's will decrease in voltage over time:
(EXAMPLE NO REAL VALUES)
Decreasing like from
5,5 to 4,5 over the 100% battery load, so you know if your at 5Volts you have about 50% left (there is a bit more calculation requiered, but you get the idea)
The battery used in new gen phones keep a working voltage of 5,5 V until it reaces about 20% load left, in the other 80% it will decrease verry little and so it is verry hard to detect the battery load.
So I should just leave it and see if it ever decreases then?
I'm just afraid because this happened with my Universal.
1. what happened to you Universal??
2. just let it wait for a day and see what happens. else contact HTC
My Universal was crashing when I charged it so I got a new battery. Since the beginning that battery showed 100% charge all the time. I then put it on to charge overnight and it showed the correct battery level.
However, my Orbit was on charge overnight and the battery level still shows 100% - after charging, and now - several hours later after a couple of calls.
What happens if you remove the battery, howmuch batt level does it show

I think you'd better contact HTC...
After removing and replacing the battery it still shows 100%.
Also what do you mean by contacting HTC? I've looked on the support section of their site but they give no contact details there. Only their European HQ.
So? you dont want to be helped by a european??
Just try mailing them, i reported some issues by mail, they are quick with the reply's so just give it a go.
I meant that normally a company headquarters does not concern themselves with support. Also there is no email address given - were you suggesting snailmail?
Looky here
Customer Services
Technical Support by email
should do the trick
Ahh, good stuff. I will try that too.
I did contact the HQ and they gave me a number for a technical support line, the person there suggested a hard reset. I'm going to try this email thing first because I'd like to avoid a hard reset if possible.
I have also had an idea. This didn't seem important to me at first because I did the same with my previous HTC devices (Alpine and Universal) but when I got the phone I plugged it in to charge and started the setup of WM5. Is it possible that when you're doing the WM5 setup it takes a reading of the battery, for calibration purposes, and it assumed it was at 100% when it was really quite low? So now it thinks that say 20% is full, so it shows 100%? Just a thought.
sounds odd, because then you could never use a new battery, coz it will never know how much it's loaded.
I've also ordered a new battery from eBay, because it was only £10 and it came with a standalone charger. I figured I might as well try it and if it doesn't solve this problem at least I've got a spare battery.
It's showing 99% now. Things are looking up. I don't think I did anything in particular. I'll see how it goes on.
http://phandroid.com/2010/12/25/you...is-lying-to-you-and-its-not-such-a-bad-thing/
First of all, bump charging is not good for your battery, but considering you can buy one from ebay at the same cost as a hamburger combo meal, I think I am willing to skip a lunch to replace my battery every year.
One technique that has gained popularity in the user community is “bump charging.” To bump charge a device, turn it off completely, and plug it into a charger. Wait until the indicator light shows a full charge (on the ADR6300, for example, the charging LED changes from amber to green) but do not yet turn the device back on. Instead, disconnect and immediately reconnect the power cord. The device will now accept more charge before saying it is full. This disconnect/reconnect process can be repeated multiple times, each time squeezing just a little bit more into the battery. Does it work?
The following chart plots battery depletion after the device has received a hefty bump charge (6 cycles) and then turned on to use battery power. Note that the system does not show the battery dropping from 100% until well over an hour of unplugged use, at which point it starts to steadily decline. Again, however, it should be obvious that the battery gauge is not syncing up with reality. How could the rate of depletion be increasing over the first 5 hours while the rate of current draw is relatively steady? And why does the projected battery line separate from the reported levels, but then exactly mirror the later rises and falls?

The answer, of course, is that bump charging definitely works. Rather than anchoring our projected values to the first data point of 100%, what happens if we anchor against a later point in the plot?
Aligning the data suggests that a heavy bump charge increases initial capacity by approximately 15%. Note that the only other time that the lines separate in this graph was once again when the phone was put on the charger and topped up to 100%. Just as with the first set of graphs, the phone kept reporting 100% until it was unplugged, dropped rapidly, and again caught up with our projections.
So what does it all mean?
If you absolutely need the highest capacity on a device like this, you will need to bump charge. There are currently people experimenting with “fixes” for this, but I have yet to see one that works. Be warned, however, that repeated bump charging will wear your battery faster and begin to reduce its capacity. If you are a “power user” who will buy a new battery a few months from now anyway, this presumably isn’t a concern.

How has this been working? I was using a V7 Kernel from that site that used TRICKLE charging.. NOW I read about the bad effects of trickle charge and batteries so I decided to try BUMP CHARGE since it doesnt leave voltage on the batery all the time. I jut know know the effects of bump over trickle and if one is better/safer then the other..
any update?
Hi All,
I have experienced something wrong with my HTC one x (upgraded OTA). It is off automaticly when reached around 40-60% battery. it happens randomly but mostly around it.
when i turn on again, it is just start till the unlock screen and it suddenly OFF again.
I have to plug the charger first and start again to make it live.
when i checked the battery while charging from the sudden death. it is charging from 35% power which it means there is still a lot of power.
when it is charged full to 100% it is automatictly off again when reach around 40-60%. In these case it off at 65%, please take a look at my battery log at the attachment.
Does anyone experience the sama thing, please help me to figure these out.
thank you so much for the attention.

Uhm I'd suggest you try a battery recalibration, it might be some issue with the software! Try letting your battery drop to 0 % (I really mean that the phone falls out because of zero power, then reboot it untill it no longer reacts), then the phone is completely empty.
Then recharge it again to 100 % (let it charge for about 8 hours).
But to make sure you bettery just google "battery calibration" for a good guide on it!

thank you so much for the tips, right now i will try to make it really empty and charge. one question when it is already full should i unplugged the charger first and then calibrate or i just calibrate with the charger plugged on?
it is still happen and my phone shuts down by itself randomly around 40-60%.
is there any other solution i can do to get rid these battery case anyone?
Have you tried clearing Battery stats in recovery, then let it drain till the phone shuts down, then charge till full while the phone is still off... The LED will turn green once it's full...
If still same problem, charge till full again, turn on Airplane mode and run the battery test, on your dialer key in *#*#3424#*#*, click "Accept" then on bottom right tap on "More", select Battery test and click run
my battery pass the test but the status of it still error. it will shut down by itself when comes to 40-60% randomly. TT i have never experienced my phone low battery or red. it dead already around 40-60 so i should charge it.
I posted that then I saw your thread:
http://forum.xda-developers.com/showthread.php?t=1706811
How many use this option? If so, is it worth stretching battery life to decrease the time between charging?
Really its the first time i saw it.
I left it off.
I use all my phones the same and havent seen any battery problems.
So i dont see why this one should be different
I turned it on for a day, but this isn't the biggest battery on the market, so I'm leaving it off.
I use it. Prior to this being baked into One UI, I got into the habit of charging my devices to 80% and it grew on me. It's a tip I got from the Accubatery app. It's a simple way to add less wear to your battery.
Oddly, my phone fresh out the box with only 5 charging cycles from 15/20% to 80% has an 88% battery health score. My Fold2 which I had since launch has a 96% battery health score...
There is no consensus as to whether to use this option?

It's all dependent upon how you use the phone. Turning it on will absolutely be better for your phone, but you will lose that 15% battery life. Your charging habits also matter. If you're a person that just always puts it on a charger when not using it, you would see more improvement from turning it on than someone that only puts it on the charger when it's low. The benefits are minimal. It shouldn't largely matter, but if you keep the same phone for many years it will help improve its life.
It's early days with the device so battery performance is still an unknown for a while longer, but I enabled the battery protect option from the start. As of yesterday I'm able to get 5 hours of SOT with the maximum charge at 85%. That performance holds up over time and I'll end up leaving the option enabled.

It is a very useful function. I think maybe I'll introduce the Note20 Ultra as well. What version does the Samsung Device Care application have for you?It's me 12.3.00.30.
Thanks!

I use the protection when I'm home, 5 days a week. I just place the phone on a wireless charger when not in use during the day.
When I'm going out, I'll turn it off to get the full 100%.
Frankly I love the option to do this. I used to use an app that notified me at 90%. Now I don't need to bother. My only gripe is that I can't easily set a toggle for the setting. I'm planning on finding the setting name with adb and using tasker to create a toggle, preferably on a weekday frequency
I turn it on because I usually charge overnight. Leaving phone trickle charging at 85% is less detrimental to battery compared to 100%
i use it, still got 5hrs sot
Got a doubt. Does the Battery Protection Mode works when the phone is charged in switch off state ? By switch off I mean completely switched off not just locking the screen of the phone.

Hi guys
I moved to LOS in the hopes of improving battery life but it's been pretty bad. I'm at my whits end. I tried using PhoneProfilesPlus to turn off all sensors and radios overnight but it didn't help. My phone literally burns through battery after every even small charging cycle. I used GSam Battery Monitor but couldn't identify any specific app to be the culprit either.
Last night I even used "Battery Tool" to stop most all apps as well as "SaverTuner" to change the Doze mode settings but even still I get the following usage curve:

Btw the times seem to be completely off too. The last charging spike was around midnight.
I also noticed that Wifi won't show as "off" in the stats unless I reboot my device. But doing that didn't change anything either. As you can see, after I rebooted in the evening, the curve was practically flat. After charging a bit and unplugging before sleep though the phone immediately started draining again.
Any help is very appreciated. It seems I can't go back to stock bc of the A13 bootloader but battery life wasn't much better on stock either.
You also have other helpful charts in Gsam.
What do you mean by "unplugging before sleep"?
Turn off your phone completely overnight and compare the charge before and after.
I meant that I don't leave the phone plugged in overnight. Sadly I can't really gleam anything helpful from the statistics. I'm going to try and charge it to full before this night and set a custom reference point
Looking at that graph, do you have your screen always on? The 2-3 hours around midnight show screen on, but no battery drop. I assume you had it on charge at that point?
What charger are you using? I use an Anker 5 port Quickcharge 4 charger with a USB-C cable that has an LED display to show the charging wattage. I usually get 18W (9V*2A) which pushes charge in quite quickly.
I can't speak for LOS20 as I'm on stock A12, but the battery does seem to discharge faster than you expect.
I use AccuBattery to monitor the power usage and charge/discharge history. Put it this way, I find I do a number of smaller charges through the day. Driving along, I'll have the phone hooked up to the Android Auto slow charging it while I'm using it. I get home and I'll stick it on charge for 45 minutes to boost it up from 20% to 80%.
The rated capacity of the battery is 3905mAh, and AccuBattery is estimating my current battry capacity at 3443mAh, a reduction of 12% in 9 months. That's with only charging between 15% and 80% most of the time. I'll give it a 100% once a month or so.
Thanks for your replies!
I'm thinking something is really wrong with deep doze in my case. I charged my phone fully and got to 50% in a day's use. I made a point of not plugging it in at all because normally you'd expect it to survive on half a battery but no dice. it just starts burning through battery suddenly.
I'm honestly unsure about this graph too. I certainly didn't use the phone and the screen until 2am. I might need to look at other apps too but that doesn't change that my pone went from 55% to 0 in about 6h.

You didn't have to use. Apps and services do it for you.
