Please vote mentioning your charge cycle count along with actual capacity vs the rated capacity of 4905 mAh/18.88 Wh
That's an interesting topic. With my P4 XL, I won the actual capacity lottery and had a phone that started with 109% capacity.
My P6 Pro has (according to 3 weeks of Accubattery) about 102% actual capacity (~5110 mAh) after 21 sessions with ~1100% charged (~ 55000 mAh).
The design capacity by the way, as you can see in your screenshot, is 5003 - not 4905 as per your statement.
4905 is the MINIMUM amount that Google accepts/offers, 5003 is the "typical"
-> (typical = design)
I'd give it a 3.6
Not great, not terrible.
Wondering how everyone's battery capacity has been doing. Out of the box Accubattery stabilized around 99% for me but now after 4 months I've dropped to 95% (4755mah). This is much faster degredation than I typically see on my devices. 95% of the time the phone is between 20-80% charge, my chargers shut off at 80% unless I know I'm going to need the extra capacity. My unit runs hot quite often and Im thinking that it is wearing out the battery with all the heat. Curious what other users are seeing after some months of ownership.

Mine started at 102% and is now at 101%. Got it when phone was 1st released in Oct..

Good to hear you are having more luck, 1-2% per year is what I am used to seeing on past devices under similar usage patterns.

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?
Sent from my Desire HD using XDA App
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.
Im using an sbc kernel on extended battery and use battery monitor widget to watch my charge. The phone gets to 100% amd then i continue to let it charge all through the night and when i wake up and look at the widget the battery constantly stays at 4196mn-4198mv. The battery gets the full charge to where it stays positive pulling 0mA-2mA to keep it full, but it never charges to a "FULL" charge. Why is this and how can i get it stay at 4200mv or more? Ive calibrated the battery multiple times many different ways as suggested by others and still not the full charge im looking for.

4200 is full. You don't want to charge it over that. Don't worry about missing a couple mV. It's perfectly normal.
I c. Id like to see it at 4200 though, so how can accomplish that?
Sent from a guy on an Evo w/ MikFroYo 4.5
You probably can't.
I need like the tutorial on maH, etc with battery widget. Like, now I'm at 100% showing 454mA, 4150mV. I have no CLUE what that means.

mAH is the number of milliamps that a battery can provide over a certain period of time. We have a 1500 mAH battery. In theory, if a phone were drawing a steady 1500 mA, the phone's battery would last an hour. The 454 mA you saw is a snapshot of how much power your phone is drawing at the moment it was measured, and it will fluctuate. If your phone stayed at 454 mA, you'd probably get about 3 hours of battery life. When my phone is asleep and idle, it usually draws about 50-100 mA.
To the OP, I did actually see 4.2 mV today on my phone as it approached 100%, but I really don't think it's something to worry about. It actually had dropped back down to 4.19X (x=something, don't remember) by the time it hit full. The mAH rating is what determines if you're full, I believe. If that's at 1500 (or in your case, whatever the extended battery's capacity is), you're good.
Thanks, man!! I Was just getting ready to put up a post asking for an explanation of the maH thing and how to read what the Battery Monitor Widget is telling me

Mines gets over 4200 but not by much. Really I would prob be happier if it bumped 4200 and stopped but I have no adverse affects. Its charging cool enough to make me happy
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.

Hi users of HOX,
I have owned this HOX since last April and I was wondering if anyone has the same problem.
From what I know, the HOX will get less charge (around 200mAH instead of 700mAH) when the percentage reaches the 90% mark.
However for my HOX, the reduced charge rate seems to start at 70%.
Does this mean that my battery capacity/life has been hindered and reduced?
Attached is the graph of my battery charge overnight.

Clearly, the slope became a hill at the 70% mark.
Anyone understands what does it mean?
My HOX can't even last more than 5 hours because of this it seems.
P.S.: I am using ICJ421 v1.3.1
it wont make any difference, just means that the last 20 or 30% charges slower - does not affect capacity.

Last 20% or 30% charges slower? But it wasn't like that before.

Charging of Li-Ion batteries is in two* phases, constant current, and then constant voltage. During constant voltage, the current will drop off from around a maximum if 1A to nothing (it's not linear). So that's normal. You should expect to see something like a 20% reduction in capacity after 1000 charge cycles.
*Technically there is a third phase that keeps it topped up, but that's not really relevant here, and it's just a repeat of the last bit of the second stage, after capacity has dropped a bit.
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
