Laza Zcell NFC 3800 mah Battery - T-Mobile Samsung Galaxy S II SGH-T989

I ordered one of these batteries on Thursday and it arrived on Saturday. It shipped from Indiana and I am in Chicago so your shipping times may vary. It was $19.99 on Amazon and I did not buy the case although I still might.
I have been running AllStars V5 since the day after it went up.
Day one:
Decent packaging definitely something I could see at a store. The battery itself is heavy, heavier I think than two stock batteries. The back cover is solid plastic with a rubberized coating on it. It still slips around on a table but feels very good in my hand. The extra bulk of the battery and case make my phone easier to grip and combined with the weight makes the phone feel much more substantial almost more well built. I was a little worried about the speaker as the back sits about centimeter further away from the speaker than the old one did, but the new cover has a sort of resonator chamber built in to direct the sound to the speaker grill. I might be imagining it but the internal speaker sounds a little better with the new cover. I do feel that the rubberized coating is going to wear off over time but we will see.
Installed battery at on one in the afternoon. Came with 76% charge. Used it normally the first day and at about 3 am it still had over 40% charge. Ran it down the rest of the way playing angry birds and using a flashlight app. Total time 16 Hours 6 Minutes. Quite awesome.
Day Two:
Pulled the phone off the charger at 2 PM with 100% charge. Set screen to always stay on and used phone to stream music over WiFi using a combination of Pandora, Songza and Google Music. Phone remained this way until 10:30 PM when I got off work. Phone still had 50% charge. Once home I ran the battery down the rest of the way using a flashlight app. Total run time 12 hours 57 Minutes. Equally awesome.
Days three and Four:
Pulled phone off charger at 1 PM. A few short calls some texts about an hours worth of streaming music. Nothing crazy. 65% as of 11:26PM. I am not going to charge it untill it dies.
Total run time 1 Day 13 Hours 58 minutes. Light usage as I was busy upgrading my MacBook to Mountain Lion & Windows 8 and my PC to Windows 8.
Day 5:
Phone died while I was sleeping and I was only able to charge it for a few hours before work. It is currently sitting at 45 %. I am planning on seeing if this gets me through the work day without any more charging.
Update:
I've fallen into the habit of charging my phone every other night. I really do not use my phone too terribly heavily. Anyhow last night was a charge night. Today I only got 12 hours of use. By use I mean pandora for the 7 hours of work and travel too and from work and some browsing of flip board here and there. If it fails again we will see how this companies RMA service is.

Do u have any real life pics of ur phone with battery on. Also i guess u gonna be caseless
I was looking at the case and it does really not protect that good. If u look at front screen shot u can see the silver from the top of phone and the bottom. But i will order the battery

I have this battery as well with the standard back and I have been thinking about a case but as of right now its been a pleasure to use. When I had the nexus extended battery I was worried about battery life. Last year my family and I too a family trip 3 states south from where we live and on that journey my phone roamed the majority of the time killing my battery life. With this battery, if we have to make that trip again then I feel confident that it will survive the trip with easy. I am a heavy user with all my radios on all the time and I get around 12 hours with 33% left average so I would recommend this battery pack its worth the money

I have this battery too. It has worked well for me. I no longer have to charge twice a day.
There was also a case available on ebay which isnt very good but offers some protection for the phone. I have been unable to find any alternatives.

Stock battery or my seidio 3500?

So!
Today I tried to make it through a day with the stock battery over my normal daily driver battery, my seidio 3500 battery.
Here's what I got.
I am a pretty heavy user, using music for a couple hours a day, browsing the internet and xda forum app a couple hours a day, youtube, and alot of other miscellaneous games and other apps.
After school (in which I don't have the best service, during one class I even have to put my phone into airplane mode due to lack of service in one building) I had around 25% left. Normally with my 3500 I'm around 60-70 depending on if classes are boring or not. Normally in chem, c++ and differential equations i'm on my phone (so roughly 5 hours of use) and then I have a break where I use the phone as well.
It's now midnight and for me my phone is at like 5% and although I made it through the day, had I not been plugged in for flashing the night build #40 for CM7 I'd be dead easily.
So what's the point of this thread?
Just to sort of give my experiences with the stock battery after using the giant beast for around 5 months.
Any questions about the battery I'll try and answer!
was running cm7 39 today and also using the incredikernal with smartass on.
I'm a pretty heavy user as well. I have 2 stock 1300s and a Seidio slim 1750. I had originally considered a 3500 but I couldn't bring myself to fatten up my phone. I work 12 hour shifts and I usually burn through one stock battery between 4 and 6 hours into a shift, then switch to the Seidio, which usually carries me til I go to bed (around 8 or 9 hours). Or if its a late night, I can fall back on the other stock battery once the 1750 gives up the ghost. I know it seems like a lot of batteries to carry around but, I have to say, I feel like its worth it, considering that my phone is comfortably pocketable. I usually keep the spares in my lunch bag or my truck til needed.

definitely i can see most peoples reason to not get the 3500.
I got it cause I don't really have a problem with having a bigger phone, and I kinda like the way it feels with the larger battery cause i have really big hands and so the stock back + battery just feels to small in my hand =(
I just am glad that the incredible has alot of battery options =)
I use an 1800 battery and when that dies i switch over to my stock. Its not too bad carrying an extra battery and i rarely use it the 1800 usually gets me through the day.
I can definitely see your point regarding the feel of the thicker phone in your hand. I had never thought of it in that aspect. I have large hands as well. If I find myself in the market for a new battery in the near future, I may try a 3500 out. On a side note, and not trying to hijack your thread but, I noticed you're running CM7 as well (I just flashed it yesterday). I've had a few fc issues but over all, I'm loving it so far. And I do think it may have had a positive effect on my battery life, over CM6. I've been running my Seidio battery for about 8 hours now and I'm only down to 50%! And it's definitely on its way toward MIUI in terms of built in features.

Seido 3000mAh battery?

I'm wanting to get one, but I can't find ANY reviews online for it. Has anyone used it before?
Anyone at all?
3000mAh is scam.......should be good for about 2400 max
Had one for about 2 months now. I get about 24 hours of very heavy usage. Internet, numerous phone calls, texts, slingbox over 3G, and using power amp for hours on end will usually have me recharging after 24 hours. I could probably use it longer, but I hate to run my battery all the way down.

I have been considering an extended battery myself, but it seems all the higher quality brands (Japanese cells) are over $50. Not sure if I can justify such an expense over just having another regular battery to swap on the go.
If anyone finds a good deal on the brand name one, drop us a link.

I get about 40 to 48 hours with normal usage (few calls, data on, 3g on, push email, etc) I also have an ass of widgets on my homescreens that automatically update such as beautiful widgets, pure calendar, feedr, facebook, etc. Best phone accessory I have ever purchased.

What rom are you on? Im on stock 2.2 and it seems i could get more out of the battery when i change the brightness settings to the lowest, but im working outdoors right now and need it all the way up. I noticed a huge difference in batt life coming from 2.1 with the same settings. Seems life froyo helped a bit

Is this one that sticks out the back of the phone and needs a custom back cover so none of the regular cases work and your phone is twice as thick as stock??

Most extended batteries are like that.
Fortunately, most people who buy extended batteries don't care how it looks, don't buy custom cases to begin with, and don't care about thickness.
I need more battery life. Running Bionix 1.3 right now, and I'm constantly using my phone from about 6AM to 10PM every day with no time to charge it in between, and it's typically near the 5% mark by the end of the day, which I can't risk for too much longer.
Unless you are gaming just get an extra 1650 mah battery it is much more convenient. i had one but the weight and bulkiness was not worth to me. They do give a decent amount of use though.....

My friend has one for his Vibrant, and it might look bulky, but good god it can live long, I moderately use mine and it dies, he's using his the ENTIRE day and he's still got 35% of his battery left at the end of the school day...

Yeaaah, I use mine a lot and it tends to die by 10 now, which means I"m getting about 16 hours of battery life. By all accounts, that's a good number, but it's just flat out not enough.
accessory geeks 3000mah
ag 3000mah gives me about 80% left after a 2 1/2 hours phone call which is pretty darn good, wich the phone call was with the screen off the whole time.

[Q] Battery Case

Has anyone got a decent case with a battery in it?
as the nexus 5 does seem to have a not too good battery life.
(considering this device)
Seriously? I'm getting 14 to 16 hours with 6+ hours screen on time. It's not bad if you ask me.
Sent from my Nexus 5 using XDA Premium 4 mobile app
I agree. I'm getting better battery life than any phone I have owned, without rooting and messing with cpu governors, or adding an unwieldy 3000+ mah aftermarket battery.
Sent from my Nexus 5 using xda app-developers app
wow
from what I'v heard in reviews its not great, was about 5 reviews.
hmmm, Ill look into that a bit more
also geekphone.com is showing a not too great battery life
No, your not wrong, the phone is going to have less talk time than some of its larger battery packing competitors given the same use, physics works as they say. I'm on the lookout myself but have yet to see anything.
It could could be a software and hardware thing, as samsung does take a big dump on android. Pure android and especially 4.4 theoretically should have a lower power consumption.
how long does it generally last when mid-heavily used?
I can't comment on battery life, but I can tell you you won't be seeing a battery case. Only 2 products sell enough to make it a reasonable expense to develop: The newest iPhone, and the newest Galaxy S.

I disagree, my DHD had quite a few and it didn't have that many sales (probably less than nexus 5 in a month or so)
I'm getting much better battery life than any previous phones I've had. I can squeeze about two full days out of it with about 3-4 hours of screen on time. If I use it a lot (6+ hours screen on) or do battery heavy tasks (play a lot of games, talk on the phone a lot), then it still lasts a full day (from wake up to sleep). Unless you absolutely abhor charging your phone every night, I don't think it's worth the unnecessary bulk of a battery case.

Is this on stock? I understand that diff configs will have diff results. When I go to bed, I usually have about 40% left with 15 hours run time about and 1 hour of screen time. This is with two gmail accounts syncing, facebook and everything on. It's not bad but nowhere near 6 hours of screen time. Especially if I play a game like Asphalt 8. The battery drops like crazy. Not complaining, but I would love to have 6 hours of screen time.
I contacted Mophie to see if they had plans to make a case for the N5. I just got a pretty generic email back but looked like they would be working on something for the N5.

I didn't make it clear enough in my post, but when I said 6 hours of screen on time or battery heavy tasks, I meant one or the other but not both. If I play games or do a lot of battery heavy tasks,t hen it doesn't last anywhere near two days. I might get 6 hours screen on time if I don't play any games, make no phone calls for the day (which is odd, I do admit), and mostly browse the internet, text, view pictures, check facebook, things of that nature. On average, I get anywhere between 2-4 hours screen on time with usually an hour of gaming, mostly texting, browsing, and other small stuff like that. It usually lasts me 2 days. It's not fantastic battery life, but definitely better than my S3 and my Atrix before that.
EDIT: I didn't use my phone much at all today. I've got about 10 minutes of phone calls and an hour of screen on time, 13 hours total, and I'm sitting at 72%. You might want to check what is using the most battery in your battery settings or download an alternate app. Screen is typically using 2 to 3 times more than the next thing under it (which for me is WiFi).

sudden battery life swan dive on both of my newer hwatches

i have both a silver and black hwatch, neither of which are more than a few months old. ive had a hwatch using the same mostly black watch face and the same brightness and tilt to wake settings since 11/2015 so im pretty familiar with my battery. normally at the end of a day im at 40% or so, 25% if its been a really long 18-20h day. plenty of battery to never worry about having to get it to a charger mid-day, even if i got out after my 12h shift at work. last wed i was wearing my black watch and leaving said 12h shift and noticed my face was dark, and my battery saver was on because i was only at 9%. didnt think much of it, every now and then i have a hiccup and a simple power cycle and full charge fixes it. but the next day my silver one also was struggling to make it through a non-work day. i hadnt made any recent changes or installed any new apps. the fairly terrible wear battery stats listed watch idle highest at around 7-8%, followed by screen, daily tracking and up at 1-3% each. i dont use the daily tracking app, but there doesnt appear to be a way to disable it, so no new pattern changes. my pixel did upgrade to oreo on 8/21, but i had no issues that day or the next. figured a factory reset may be in order, so i reset the black hwatch but the same problems persist. im not usually getting quite down to battery saver by the end of the day, but i definitely need to put it on the charger as soon as i get home and today my silver watch did run all the way down kind of out of nowhere, since it didnt come off the charger until around 10am and was at 15% by 10-1015pm. any thoughts?
They are simply useless watches!

Unfortunately my new H W2 Classic (bought only 20 days ago) battery life is about 4-5 hours when worn on hand, ADO ON, WiFI OFF, Brightness 3, Wrist Gestures OFF, Tilt to Display is ON.
At these same settings when i place the watch on my table, it will last for less than 6 hours and I wake up to a watch running on fumes!
I am returning it as I read so many people have done so with defective batteries, MOST certainly.
Good luck finding someone willing to share any real useful info, AS no one seems to know what the heck is happening!
Personally, I think these watches are CHEAPLY BUILT.
MY SMASUNG GEAR S3 IS NOT MUCH BETTER EITHER, though it is supposed to be KOREAN!!!
I am really disappointed with these HUGE names who fail to make a simple watch! TAKE A LESSON FROM APPLE! Limited functionality but even their Model 2 (which I have) does more than these watches and with real battery life that lasts at least a day!
Now, we wait for Apple to make their watches run on Android!
One thing to note, as I am writing this response I noticed the Power Usage on my watch increased 3% by Google Play Services and my battery dropped from 83% to 79% in about 3 minutes! Sure at this rate I will have no power in about an hour and a half! Could it be Google Play Services killing these watches?!
I've always had fantastic battery life on my original until the last few months

[review] ZeroLemon 8500mAh battery case

Edit: TL;DR this case delivers. It's big and bulky and the excellent battery life of the Pixel 2 XL makes it somewhat unnecessary in everyday use, but if you're anticipating an extra heavy day or want to get away for the weekend without a charger you should be able to get by with this.
ZeroLemon sent me a review unit which arrived yesterday. Initial impression is that this thing is huge. The phone is still usable, though I can't imagine trying to do anything one handed. The fingerprint reader is accessable but a bit of a reach. I can cram it into my pocket, but not easily. None of these things are unexpected though; it's an essential trade-off when trying to cram a massive battery into a case. I've had several ZeroLemon cases in the past including for my Pixel XL and Nexus 6P and this case is pretty much the same in fit and finish: a large, heavy battery that has a removable TPU outer skin. The case charges via USB C, which can pass through to the phone. The case will not fast charge the 2 XL since it outputs at 5V/1.5A. Keep in mind this isn't a bad thing; this is meant to be a case and not a portable charger so a fast charge isn't needed and long-term should be a bit kinder to battery health.The case itself charges at 5V/2.1A.
Due to the size you will lose a few things, namely NFC (update: maybe not true, see next post) and the ability to use a USB->3.5mm adapter. This means no Android Pay, if that matters to you. Again, this is a trade-off with a battery case and is nothing unique to the ZeroLemon. Also, don't let the size lull you into thinking this is a rugger case akin to an OtterBox. It will offer your basic drop protection, but not much else as it's essentially a thin TPU case that just happens to be wrapped around a massive battery.
Some background on my usage: my 2XL generally gets great battery life, and even with 4+ sot I rarely need to plug in during the day. I don't do any gaming so my screen time is web browsing, messaging, streaming music and some light video usage. I gave it and my phone a full charge overnight and will be attempting to make it through the weekend with normal usage and not charging with anything but the case. Check the next post for updates and results.
Edit: For some reason XDA isn't letting me attach pictures, but here's a link. My 2 XL is wearing the Ringke Slim in the comparison shot.
https://photos.app.goo.gl/DhtfRvu81VSeUTNm1
Update 1: My phone came off the charger at 5:50a and at 7:30p I was down to 35% so I turned the case on. By 8:30p and with some light usage the battery was up to 80%. Not quite rapid charging, but not bad at all. Also, fun find, I stopped by the store on the way home and tried Android Pay even though ZeroLemon claims no NFC. It took 2 tries, but it worked, so unofficially you can still use NFC.
Update 2: Day 2, the phone was at around 75% when I woke up at 5:50a and I again let it drain to 35% before turning the case back on, which was at 5p. It took 2.5h to fully charge and the case is still showing 3/4 LEDs, so somewhere between 50-75% full. Between the amazing battery life I typically get with this phone and how big the ZeroLemon battery is I have a feeling this is going to take a while to fully drain. Maybe I can make it a week?
Final update: Day 3, I turned the case on a bit early today at 44%, and it charged for exactly another hour before the case died. This added another 42% to my battery.
To recap, the first two days I charged from 35% to full, which took 2h31m and 2h29m respectively. Each of the first two days the LEDs dropped by one. Today I only charged for 1h, from 44->86% and the LEDs went from 2 to empty. I remember LED calibration being a bit off with the Pixel XL case as well, so keep this in mind. Still, my phone has been off the charger since 6am Sat morning and at 8p Monday night I'm at 55%. I've had nearly 7h of SOT including streaming the 3rd period and OT of the CBJ/Caps game on Sat over LTE, several hours of listening to both streaming music and downloaded podcasts over Bluetooth, plenty of browsing and measaging, and maybe an hour or so of calls. I didn't try and use my phone any more or less during these past 3 days, so I'd feel comfortable using this case for a weekend trip without charging. The size is prohibitive for me, and frankly the 2 XL gets such great battery life that I wouldn't have use for it on a daily basis. But for extended periods of time away from a charger this case gets the job done comfortably.
I remember on the original pixel all the battery cases would prevent the phone from going into deep sleep. Is your phone able to go into deep sleep with the case attached either when it's charging or not charging?

that is for mentioning this. I meant to mention that in my intro post, but totally forgot. so far it appears to be sleeping properly. in my daily use I often have something running the background (sleep as Android at night, music during the day, etc) which limits how much it goes into deep sleep, but I am seeing a good amount of deep sleep listed with accubattery. once I run the case battery dead I'll do a proper test of the sleep.

yes, it sleeps properly. I just left it alone for an hour, with the case powered off, and it slept for 49m
