Really like my anker 1900mah batteries

I got the charger and 2 batteries from amazon, and have been running them for over a week now. In that time, my phone had not touched a charger! lol
So far they last a long time and do not heat up. NO JOKE, my phone is 27 hours with 33% left, with light to medium use.... that's reading mu pules blogs, playing some games, surfing the web, chacking emails, and facebook, using it as a flashlight a few times and checking out the market for new apps. The batteries are good quality as far as I can tell.
running wanama light ROM or whatever, with nephetamine kernel.

Are these batteries the same size as the original?

1900mah, I got 1 day 14 hours out of my battery with good use, and switched my battery and I just kept on trucking! lol My review is on amazon as well.

I meant are they the same physical size as the original 1650mah samsung batteries, or will you need a larger back case

same size. you use your existing back case your phone came with. I find it lasts slightly longer then stock.
After a couple of cycles the battery takes 6-7hrs to trickle charge in the dock charger.
But its hardly an inconvenience when you have 50% battery in your phone and a spare battery in your back pocket just incase and a battery charging at home on the dock charger.
and I never have to connect my phone to a charger either.
Great!

Anyone here been using them for more than a month and noticed a drop in capacity?

screenshot of battery usage? =D (specifically display-on time)

Just got these in. I'll report in a few days how these act under heavy usage. ie 3+ hours screen time

Nice to see another member from sg. I have used to for almost 2 weeks now.
So here's what I think. (its not an official benchmark test)
Using CM7 and launcher pro
Wifi or 3g switched on all the time
No GPS
Alarm Clock Plus running the whole night.
Casual games and surfing.
No video watching.
No calls, no text,
About 2 hours of music
24 hours later, ~15% left.
This performance is about the same as the stock battery, so you should not expect a drastic improvement. But with a total of 3 batteries including stock, you can pretty much do whatever you want during the day and charge when you need to.
One good thing about this arrangement. You are always charging your battery only when its empty, so i suppose battery life will last longer?
For the price and functionality, its a very good buy.
Update: It does heat up considerably when i stream videos and battery life dropped 15-20% for every 25 min of streaming. It could be a rom thing and not the battery's fault.

Aside from how well the battery performs, which I won't comment on as I don't own one, your statement about 'charging your battery only when its empty, so i suppose battery life will last longer?' is actually incorrect.
Lithium-ion batteries are more conducive to a partial discharge than a full one. The only time you ever full discharge your battery is to calibrate the battery meter, normally once every few weeks of use. Constantly draining the battery to 0 and then recharging it will actually harm lithium-ion batteries.
As stated here, http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries 'Lithium-ion does not need to be fully charged; a partial charge is better.'

I've had my anker battery for well over 2 months now... Runs cool (Almost never heats up), and with very heavy usage, lasts me all day... I can go 2-3 days on one charge if I just use it for calls + texting lightly. Love it!

Anyway do you guys fully discharge your battery on the first use? as i assume they come mildly charged.. I'm waiting for my batteries to come!! so excited

Sorry to disappoint, I am studying in the states so its a simple click on ebay.
Here's the link http://www.ebay.com/itm/Anker-Batte...ccessories&hash=item336b95eea6#ht_4700wt_1200
They did mention that they ship world wide so you will have to ask them. PM if you have more questions since I seldom check this post.

I should have wrote a disclaimer that I am not 100% certain if that increases batt life. I am not so sure that it'll harm the battery if you perform full charge discharge, but i do know that the cycle means you are using pretty much calibrated battery all the time. For people interested in finding out more, that article is a good reference. Make your own judgement after reading it.
Thank you for posting the article btw!

Thanks for the eBay link!
I just ordered mine literally two minutes ago from Amazon.com. Don't know why I forgot to check eBay. I guess I was going to buy a few things for Amazon anyway. Hope I can still cancel my Amazon order as it's $10 cheaper to order from ebay.

Ive had mine for a few weeks now and definitely better than the stock ones for sure! I have not charged my phone at all since I got this lol

Important to note that you can't charge these in the phone, and you have to use the external charger. I can see that being inconvenient in some cases

Battery Life atrocious

Fully charged my LTE Nexus while it was on and then fully charged while it was off. Restarted the phone, haven't done anything with it in 30 mins and it's already down 4% to 96%. What's the deal?!?!?

Someone said in another thread... if you look at your Android System usage in the battery meter, its way too high... sounds like a bug - apparently a custom kernel has fixed this, but I havent rooted yet to test it.

Although I prefer the GN, laptopmag.com found that the Rezound and RAZR have clear advantages when it comes to web surfing time on 4G. GSM GN wasn't too impressive either.
"On the LAPTOP Battery Test (web surfing over 4G on 40-percent brightness), the Galaxy Nexus lasted just 3 hours and 40 minutes. That's a full 3 hours less than the smartphone average (6:38), and about 1:20 less than the unlocked Galaxy Nexus on T-Mobile's network. By comparison, the HTC Rezound lasted 5:03 and the Droid RAZR lasted 4:48. Verizon Nexus owners may want to turn off 4G when they don't really need it or find other ways to conserve juice."

After just a couple days mine is doing just fine. I'm at 18 hours right now with 23% left. You have to condition the battery always.
Mine did the same thing as they always do. I only got 4 hours first full charge. After 2 more full cycles it's great!

I forget this every time I get a new phone!! It's odd considering I load roms very, very frequently on whatever phone I have at the time and I know I have to wait a couple of battery cycles for battery life to get acceptable with any new rom, but I can't seem to remember it with a new phone!
I'm going to chill and wait and see.

Also, let it die completely and then charge it up 100000% (leave it charging overnight if you can). This is a good way to "train" the battery.

Do NOT do this whatever you do. You should never completely drain a Li-Ion battery except when calibrating it after flashing a rom. Draining li-ion batteries hurts its battery life.

Ok, so should he do it or not? You say not to unless you're calibrating.
Well, that's what the other poster is talking about. "training" = calibrating.
It doesn't harm a thing letting them drain all the way to the point of the phone shutting down. I've been doing this for all my phones, new roms, etc. I always end up with excellent battery life.

Sorry, but you are wrong.
Deep discharges do "harm" a LiIon battery physically (there is damage done to the membranes in the battery at a molecular level).
You will get about ~500 full (deep) discharges from your battery, but you will get more than double of that if you only discharge to 50% and more if you discharge even less. So the best thing is to charge your LiIon cell as often as possible, with the exception that it's also not healthy for the cell to be at full charge voltage (4.20 V) for a prolonged time either.

Yikes. You people with good battery life are lucky haha. I'm on my 6th charge and I still get around an hour and forty minutes of battery life. I'm at like 50% after an hour or so... and that's with LTE off too...

When you guys unplug your gnex from the wall... (gsm)

Does the battery go to 99% for you guys instantly? seems like mine does, as soon as i unplug it goes to 99%, just wondering if its normal or just my phone, because on my galaxy s II i would get like 30 minutes of no drain, like it would stay at 100 for a while, while this phone is like as soon as i unplug the battery is already down to 99.

Calibrate it
Mine stays on 100% for a good half an hour or so too

what is the easiest way to calibrate it? any links.. my GNEX will go 99% instantly too but overall battery drain is awesome

my battery life is TERRIBLE on this thing, it drains like crazy.. i want to calibrate it super badly but im not rooted, so i cant delete batt stats.bin , i even let it drain last night completely charged it again while it was off..still same terrible battery life. its a shame because i really really love this phone.

I'm sorry but that sounds like badly calibrated battery. Lithium-ion Batteries are -never- 100% except for a very brief moment.
It is natural that your phone displays 97%-99% when unplugged (or even when still plugged in). Batteries protect themselves like this, because these batteries cannot be charged while they are full, they will stop charging the very moment you hit 100%.

Generally you don't want your battery to be above 90% for a extended amount of time, that much voltage/capacity speeds up the degradation of the cells. So actually you should be happy, because your battery will have a longer life.

He's technically correct. LiIon batteries are happiest around 60-70% charge level. However given that your actively using a cell phone battery and your not storing it at high charge its OK.
If you really want to learn more about Lithium tech I can link you to a forum where people are VERY serious about this stuff and use them for high powered lights.

This is a known design "feature."

Got an extended battery...

...and its wicked (IMO..I've heard others not have good luck with them..)
Basically, I've gotten 22 hours of fairly heavy use.. web surfing, Facebook, gaming (order and chaos mostly) among other things....using auto-brightness.
Now that I have another battery...I'm going to unlock/root and get to work flashing like I did on my DX.
A question though.. If I use my extended battery exclusively, and keep my standard battery as backup... Will my standard slowly discharge over time not being plugged in? Idk much about batteries..
Thanks so much,

It will yes, expect it to loose approx 30% over a period of a year being idle. Nothing to worry about.

Oh okay. So popping it in once a month should keep it up then?
I just want to be sure I have one handy because I once got into a corner with my DX where I needed a full battery to .sbf and mine was half dead and wouldn't work...so I had to hunt a friend who also had a DX down to fix it lol. Just want to be sure I don't run into the same problem >.>

It will lose very little capacity not being used. He meant it will lose charge just sitting there. Just don't let it sit empty. Or at full charge.

You should be fine, lithium-ion batteries hold their charge pretty well. I've not actually tested them before, but try charging it to full and then booting up to see the charge in 28 days later, might be interesting to see.
I know my Nikon D7000 batteries hold their charge very well, I tend to leave one in the camera and discharge the one in the battery grip first and just use the battery for a month or so and swap them around. In the same sort of time, 28 days I can lose up to six percent this time of year, but I am going out everyday in temperatures as low as -12°C, so it's to be expected.

For this Id like to know some additional information... what widgets you have running. Stock or ROM and what kernel. As well as settings like display, sync timing etc.

If you want to store your LiIon battery it's best for the battery to have ~40% charge. The battery will age the slowest this way.
Do not store it at 100% or 0%. Check every 6 months and recharge to ~40% if necessary.

This also reinforces what I've heard. Store these type of batteries around 1/2 charge never full never empty.

Old/Bad battery

So I got a brand new pixel XL a few weeks ago. I was reluctant about the whole thing because even though it's a new phone. It has been sitting in a box for over a year without being charged or anything. So long story short, I got the phone and the battery life is awful. I took it off the charger this morning and within 5 min of being off the charger it's at 96%. I typed this and that's it. My work issued phone is a standard iPhone 7. Absolutely destroys this pixel XL in battery life. What is your experience with this phone? Do you think it would be worth ordering a battery and putting a new one in?

Depends on what version of android you are using. 7.1.1 and 7.1.2 were great with battery life, 8.0 sucks and I have heard people in the beta 8.1 are saying the battery life is spectacular.

Something is wrong then as you have said, 8.1 is awesome on battery.
I would bite the bullet and factory reset it, and hold off putting any apps on it, or making any settings adjustments for a couple of days.
If that works, go slow adding apps. If it doesn't yeah get the battery replaced.

Battery's don't like to sit. That's why a lot of people that have cars that sit or recreational vehicle put battery tenders on them. Maybe this doesn't apply to the batteries in our phones

I don't know if all battery types work the same. Car/boat/etc. have lead-acid batteries, the old rechargeable and battery phones were nickel-metal-hydride, and modern phone batteries are Lithium Ion. They all have different characteristics when being used and stored.

Valid point. But I think a bad battery will continue to drain, maybe not as fast....but too fast for while on doze.

I've always read that the battery percentage isn't too accurate above 90%. Also, don't the phones stop charging once full and trickle as it depletes? There's apps that had been made to do this as well since it's supposed to be better for letting lithium batteries. I'd give it a day or 5 before thinking your battery is bad.

I have had the phone for a few weeks and have just been kinda dealing with it. Maybe it's fine and I was just expecting more from it. So far it just has not been all that impressive.
Edit: your comment about the first 10% not being that accurate. There may be something to that because it does seem as though the first 10% goes fairly fast then it slows down after that. Maybe it's just something g that I need to get use to
