[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.

Battery life

So far I've experienced excellent battery. I charged it fully when I got it home, and then unplugged it. Here are my results on an uncalibrated battery with moderate use except for when it sat overnight.

Not to shabby. This was with background data on, auto sync off, with the only the maps app being stopped.

Good one.

My Photon can get me 4 hrs under the same conditions. Let's hope the battery will get better after a few recharge.

From A thread over at androidCentrel posting Epic Touch usage.
Tkemack
Screen On & awake look to be on roughly 70 - 75% use within 14 hr
Photon doesn't come close to such battery performance .
I'm looking forward to some Touch custom roms Battery life will get even better.

Im in debate battery life seems decent for me but no where near what other people are posting. I got 9hrs so far and im at 20 percent with screen on for 4 hours. Dodnt play any games just some web, text and xda. Does this seem right?
The first four hours the powersaver settings were still on. So wifi on, no 3g,4g,no auto sync,brightness at 10 percent.
Last five hours Auto sync is on. Brightness is 25 percent. 3 mail accounts with mail only and I've only had 1 email pushed the whole time. 4g off. Wifi only the whole time no 3g. Screen timeout 30 seconds.

7+ hours of battery watching video

So, I got my a100 yesterday and wanted to see how much I could squeeze out of it. I manage to get 11+ out of my a500 on a plane trip, so I figured I could be effective here as well. Before I go any further let me say, I tweaked mine for watching movies on long plane rides. Meaning low light, no wifi type scenarios.
Using setcpu I down clocked to 6xx (whatever the preset clock is) and a conservative governor. Then, I set the brightness to about 10%. Then, I used moboplayer and set the in-app brightness to about 15% as well. This is still quite view-able in dark areas, like on a plane with the lights out. I ran the same movie over and over until I reached about 10%. I used a calculator to guess the remaining time left, as I needed the remaining 10% to finish up a few other things. Assuming the last 10% falls at the same rate as the rest, I would be at 7.1 hours of battery life purely watching video. Pretty good if you ask me. Hope this can help somebody in a similar scenario.

This is on par with what I get while reading and playing back music. I use poweramp to playback music off my sdcard, while reading ebooks with Aldiko.
Airplane mode turned on and no wireless on, backlight set to the lowest possible, setcpu set to 312 max, apps zipaligned for lower memory usage, tons of apps frozen from autostart and I get roughly 7 hrs (depending on if I've let it sit around for a bit).

I actually ended up getting 8 the other day with the same settings, pretty happy with that.

I have the brightness turned down to the minimum, no underclocking or anything & this was my result with just general Facebook & Twitter checking as well as this and some ebook reading. Had just plugged it in when I took the screenshot.

[Q] Is my battery runtime normal?

Hi everybody,
i'm running on Paranoid 3.6 und AK256 Kernel, and these are my battery stats.
Used the phone alot during the lectures today, tested this halo stuff (really don't like it).
But ~9h is just too little or?
System is just 2 weeks old, so pretty clean i think.

What's your on-screen time?
Sent from my Cyanogen-flavoured, AK-powered Galaxy Nexus

It was about 2.5 hours screen on time.
My stats for today are attached.
Screen on time is 3h 5min. The almost horizontal line at the beginning is in airplane mode but with wifi on.
Is this okay? It feels like that this is way too little runtime :/
Thanks a lot !

seems fine to me.

That's about average battery life for me. If I stand right in front of the wifi router + good 3G signal I can maybe get 3.5-4 hours screen on time. Else its usually about 3 hours on full wifi. Or 1-2.5 hours on full 3G or mix of 3g/wifi depending on the day and the brightness.

3hrs is my normal. Just go out n buy a separate charger and another battery or two (that's what I did) and u just have an extra battery on hand when u need it

Do I need a new battery?
Hi guys it's me again,
NOW I think my battery drains way too fast, I don't use my phone that often but I can't make it over one day!
Here are some screens, i know i've got 30 % left, but thats gone pretty soon
I'm running on Purity 5.7.1 (Android 4.2.2) and Fancy Kernel r36 extended version for quite a long time now.
Is my battery too old and damaged, should i purchase a new one?
Big thanks for any help !

Yeah, it's normal.

You're last longer then I do

Battery issue - Anyone else has same issue?

Hi guys
I've had my HTC 10 for over 2 weeks now, and as I decided to change from iOS to Android the first few days/week the battery would only last me barely 14 hours.
However, the last few days were very impressive with the phone lasting me 2 days and 12 hours with normal usage (no games and not heavy internet browsing).
But today something weird happened as I took the phone in the morning to go to work and at 10:30/11:00 my phone was down to about 60% without me doing anything to it and without a specific reason to it.
I will attach some screenshots to see if anyone had the same problem/issue.
I would appreciate any feedback you may have!

Did you try to restart the phone? Something is keeping your phone awake. A restart every couple of days is always helpful.

Yes, I did.
However, the phone's battery still only lasted until 7 pm. Which is really weird as I literally almost didn't use it...
Will see how it goes today

My battery life did not last very well either when K first got my 10. I'm an HTC lover by the way. In my experience, I've learned you really need to optimize the controls and settings after you purchase the phone to get the most out of your battery. I restrict a lot of app permissions that ask for location so my phone isn't constantly locating itself on GPS. Same for Wi-Fi. I turned off the auto scan for the Wi-Fi cause that absolutely toasts your battery. And then I turn off vibration feedback for touching keys just to conserve even more. I moderately use my phone throughout the day checking mail, texting, browsing the web, facebook, xda, altos adventures, a YouTube video here and there. I get to my office at 4 in the morning, don't get home til 3 pm and my phone still has anywhere from 45 - 60% charge. I think that's great considering my M8 normally has 15 - 20% when I would get home. Just tinker with the controls for a bit. Maybe I'm wrong but this is what worked for me

Yes, I understand and I have done so by restricting must apps and by having the same constant brightness and normally (as it happens today) the phone after 12 hours still has 50% battery. But it was that episode that literally was eating away the battery without me using the phone at all!
Thanks for the replies so far
