[Q] Charging for the first time...

1.How many hours should i charge it for the first time when i take it out of the box?

I would say charge it until the light turns green

Light goes green. Done.
All this charging for hours and hours before you first use it malarky goes back to NiCad days and does not apply to Li-ion batteries.

I left it to charge overnight, but I don't think it matters with Li-Ion batteries

Li-Ion batteries doesn't need that initial 8 hours charge.

I remember reading article on engadget saying you can charge in whichever way you like thanks to nowadays battery technology.

I know about the memory effect of older battery technology and how it isn't present (well, it's so small as to not count) but I still charge my phone regularly and leave it plugged in for at least an hour or two after the charge light turns green. I'm not the heaviest of phone users, probably very light to medium, but I get a day easily. This is from last night when I got the 15% or less charge remaining message...

I shrank the image to avoid it looking overly large. I'd like to point out I'm using stock firmware, no overclocking or underclocking and while this was longer than most charges I'm usually getting between 22 - 30 hours between charges. You might be able to do the same and get nothing like this, I'm just passing on my experiences

Well can you show us the screen on time and also whether during that 1 day and 15 hours was it on heavy internet usage?

Not now I can't because that was posted before I went to bed and the times reset when I took the charger out. As I said I'm not a very heavy user at all, I'd put myself in a perfect tablet user market but I'm waiting for better options to come out. Judging from my usage I'd have to guess at around between one and two hours screen on time. A lot of my use is basically checking a few things online, Twitter for example, reading a few articles on Engadget and the odd YouTube video.
I'm not saying the battery life is great or that using it this little is normal, but I don't purposely avoid using it to stretch the battery out so this is typical for my use.

I got a letter from my provider saying you should charge the phone for 14 hours i only charged it until the light was green 3/4 cycles of usual charging should get the battery working at optimum level.

Premature Shutdown & Random Unlock Problems

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. ?

QC 3.0 reduced performance

Hey guys,
Has anyone else noticed decreased performance of QC3.0?
I was sitting at home today and noticed the phone estimated 38 mins to get from 46% to full charge which seems a little longer than usual. I swear it used to be much quicker.
Thanks

I don't get your Problem?

So.... here we go. First full charging Benchmark on my HTC 10 completely logged with an USB Powermeter.
From 1% to 100% takes 95 Minutes.

It's always taken me 60 Minutes to go from 45% to 100%

It's slower once you hit ~80%, where it starts charging more around 5v 2A. Perhaps your cable is damaged? Otherwise the phone definitely slows down when it heats up, if you've been gaming on the phone prior to charging it will charge much slower.

You should learn how QC3.0 work first.
when the battery is low, the charger will give more input, but if not, will give a 'normal' input. cmiiw.

for me, sometimes my phone "charging" only, I have to re-plug cable to get "charging rapidly", make sure of that, wait for "quick charger connected" while screen on after seconds of connect cable, or make sure "charging rapidly" is showing "not charging only" while screen is locked.

Thanks for the replies guys.
Just to clear up, basically what I have noticed is that over the 4-5 months I have had my HTC 10 I feel there has been a change in the charging behaviour of my phone. It seems that the phone is taking longer and longer to go from 0% to 100% charge. I am aware of how QC works and that generally you get a nice spike up to 80-90% with the last 10% or so coming on much slower, however what I mean is that the actual total time from flat to full is taking longer - or so it appears.
Using all stock cables and adaptors over here - just curious if anyone has noticed the same thing.
Cheers

Install BatteryLog or batterywidget app and take a log to see how long it takes from 1% to 100%

I've had mine since launch day and I haven't really noticed a difference. I'm a heavy user, no gaming but lots of YouTube for podcasts and reading. I have used the same charger that came with it ever since, and I have a cheap QC 2.0 charger for my car, but I use my official cable for that as well.
My cable is starting to go bad, well, kinda. Sometimes it has a hard time initializating quick charge.

Thanks for the replies guys.
Here is a screenshot I have taken to illustrate what I am referring to.
I will install a battery logging app and report back.
Cheers.

Considering that it takes around 1:30h from zero to full, I think that this is normal? Is it not?

Phone just stopped fast charging?

3-4 days ago, it just happened out of the blue. Charging from 70% to 100% took 1.5 hours. I rebooted. Didn't do anything unusual in that time but updated Play Store apps. Just tested it right now - 22% in 43 minutes.
Any ideas on how to fix?

So, what exactly is the problem?

The charging appears to be much slower than it used to be.
I just checked at 45% battery. It says "Charging rapidly," but it is charging at a speed significantly lower than 1% per minute, more like 0.8% per minute. It completely stops "charging rapidly" at higher % of battery. In my estimation, this will charge the phone, 0-100, in about 2h35m. It used to be 1h40m.
I think that either the latest update introduced a bug or my charger/cable/phone usb socket broke.

Usually rapid charging occurs at a lower % and then goes away as the phone reaches a certain threshold. I think if you charge the device at 75% battery level, rapid charging may not happen...I could be wrong though...If this is a bug, then it would be all over Reddit which it's not...so it's very likely that your charger is kaput!

I've had the same issue, although not really looked into why yet.
I was using a charger I had with my 6P because it had a longer cable(official, bought from Google when I had the 6p).
I changed the cable to the plug that came with my XL, and it started fast charging, in fact faster than I have had in months it feels like.
I think they changed something in the latest May security/bug release, i'll be investigating more on my day off from work.

It should be all over Reddit, except I don't use Reddit, therefore it is not
Anyway, the Charging Rapidly does stop after 70%, however, Google algorithm still predicts 1% per minute charging rate. For example, it may say "Charging" (not Charging Rapidly) at 75% and then say in parenthesis - time to full charge 26 minutes (literally happened to me.) It still took well over 45 minutes to charge from that state.
I think there are bugs and issues with the new OS updates with regard to charging.

[FP4][LOS20] Absolutely atrocious battery life. Phone dies every night it's not plugged in

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:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

}
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.
