[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.

[Q] Is it possible to create a "bump charging" kernel?

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?

Slow charge problem

Hello, I have the problem that no matter which charger / charge cable ,the phone takes at least 3 hours to charge 0% -> 100%, the battery once charged gives me life 3-4hs sot (screen on time). Thanks

Sounds like your battery is bad. If you have the phone/battery for about a year or less, it's possible the battery is defective. If you have another battery use that one, but if you have a new battery you will need to cycle charge the battery. This means you have to charge from 0 to 100, let it deplete completely and keep doing the same thing for about 3-6 charges. This effectively breaks in a battery giving you the best longevity.

sorry to revive this thread but did a new battery work for you? I'm experiencing similar problems since the MM update, without fast charging enabled it charges at about 600mah, with fast charging enabled its about 1000mah but tapers off to 400mah once it gets to 85%
I'm not sure if its my battery or if this is a new "feature" of MM, last time that i charged from 30% it took 4 hours to reach 100% if anyone got a suggestion let me know.

3-4 hours is great compared to mine. If I use the USB cable, it'll take about 12+ hours (0-100%). Problem started after I dropped the phone. Luckily wireless charging takes about 5 hours.

Used to be no more than 2 hours before, not sure what the problem is, the battery is only a year old

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?

[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",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
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.
