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.

I know there are a million threads on battery life here and on other forums. But I am curious before I take the dive into the EVO (buying outright without an upgrade).
How bad is the battery life?
and
How wide spread is the screen separation issue?
I intend on buying the EVO and then trading to the EPIC when its released then deciding which to keep for the next year until I do have an upgrade.
Battery life will probably be the key determination for me between the 2, I need every last second of power I can get.
Captivate guys are saying 5% an hour under moderate use 2% under light- I can tolerate that. But its a GSM phone and they typically have better batter life anyway. No one can really tell what the Epic will do until we get one.
If I don't touch my phone and idle it I can get 24+ hours. light/moderate I can get 8+, heavy I pretty much have to keep it plugged in.
I got 2 days on a single charge last weekend, barely used and was basically on a 2 day drinking binge. Probably could have gone a bit longer but I plugged it in first chance I had. I can easily get through a day with medium use. Maybe light in the morning, more medium - heavy use in the afternoon but can still make it home knowing I have some charge. Or if I get sidetracked for a couple hours at the local watering hole I know I'm still safe.
I feel a lot of people want to best their last battery time though, sometimes after a decent day of use I need to juice it for a while before I go out that night. Any decent phone these days, with the things they can do, can be dried out pretty quickly with heavy use. But once you get more into the regular use of the device it is more than suitable, IMO. Not to mention other steps can be taken to make sure you get the best performance out of the phone, battery included.
I've been leaving my GPS on lately, keeping sync constantly on, just to see how big of a hit it will really deal during the day. It's not really noticeable yet. One thing I have noticed though, honestly, is that in the beginning when my phone was off it seemed to really use a lot of battery. But now when not in use it's almost as if the battery takes a very minor hit, if a visible one at all. Went to sleep last night with 70% left and woke up it was reading the same. Responded to emails, sent some texts, checked the weather for no reason, and left it idle for an hour. Still sat at that 70% mark, even though that is a slight estimate in terms of battery charge meter. Might have been nearing more to the 60 but still showed 30% as used.
this is a screen shot from when i had cm6 7.27 build. i'm running the 8/2 build right now and its about the same.

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?
Found this, what do you guys think? trust worthy? waste of money? great deal? faked reviews? not sure. opinions please

I just bought one of these. Been using it since Monday. Not sure about it yet, still bedding it in. Today is my first usage after a full discharge cycle.
Yesterday I discharged the battery as fast as possible by running stability test and I still managed to get 5 hours screen time.
Will update at the end of this cycle.

Please keep me up to date with how your usage goes. would mean a lot. very curious about this battery.
Ok still not sure about this yet. I've now done 2 full discharge cycles by draining the battery as fast as possible. I ran stabilitytest again last night and ended up with 5.5 hours screen time with 14 hours off charger. Charged it overnight and bump charged it a few times.
Today I'm going to see how it fares with normal use. Not very impressed so far though as I'm at 83% battery with 49 minutes screen time and 5 hours off charger. Light usage today with a few hours of music through wired headphones. Maybe the battery % isn't calibrated properly and it'll drop slower as it approaches midline, who knows.
Will keep updating.
I know someone with it and he said it barely lasts 20% longer than standard battery, so guess that means around 2500mah
Conclusion after 6 days and 5 cycles is that I'm getting about 25% more than stock. Not great but I got it for a tenner inc delivery so can't complain.
Shame we can't get the hyperions in the UK. Would love to get my hands on one of those.
Actually starting to like this battery. Getting decent results now.

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
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.
