GTMax 3500 mAh battery - Poor battery life still - T-Mobile Samsung Galaxy S II SGH-T989

I was wondering how many people got these on sale(12 bucks on amazon) and what results they got.
Ive had mine through a couple charge cycles now and im not impressed at all, doesnt feel like its doubled my battery life.
Im at 80% after 2 hours, with only 16 minutes of screen on time. This might actually be worse than stock. The battery summary doesnt show any major drain from apps, and go launchers running app list doesnt show anything out of the ordinary either.
Im running Faux 0.9/Juggernaut 4.1/Litening theme
Im not sure what else I can do, battery is draining ridiculously fat.

It could be just be a defective one. Some custom roms dont recognize the batter stats properly as well. Try exchanging the battery for a new one and also try a different rom. Also try Wipe Battery Stats in clockworkmod recovery.

Hmm, thats kinda scary, would reflashing a rom from scratch fix that?
Also, google has stated wiping stats does nothing, thats a recent development.
As for exchanging, its from amazon, it took 3 weeks to ship this one to me lol.
It might be defective, it did take 9 hours to charge. 3500/650 should be ~ 5.3 hours, but maybe this is why it was on sale for 12 bucks.

Yes, the myth was that wiping battery stats improves the overall battery life but I was not saying this in hopes of improving it. I was just saying to see if it will correctly display how much battery life you have on your rom because one time I had a problem where my battery life stayed at 100% and after wiping it it correctly displayed how much I had left.
If it takes 9 hours to charge then I think its very likely that you do have a defective one. Rechargeble batteries tend to show that kind of symptom when you charge it often without letting it drain first. Try completely draining your battery below 10% and fully charge without stopping (dont pull the plug). If the battery life is still the same and it still takes around 9 hours to charge then I think its safe to say you do you have a defective one.
Also, please double check that the particular battery that you have is compatible with SGS2 Hercules model. Look at the battery information and compare it to the stock one. Make sure the voltages match.

I flashed Mr X's kernel, since Faux has been off since 0.07 for me.
When i charged it last night, it was from 0%, and it took around 3 hours to reach 34%, so im estimating the 9 hours based on that.
The stickers on it say 'Replacement for Hercules T989' Li-Ion 3.7v, i dont have my stock battery atm so i cant see if its the same, ill check that later.

I find it faster to charge using the usb plug converter instead of off the laptop using the usb cable. If I were you, I'd just use the stock battery until the new one ships in. I believe that's your best bet.

I may not even seek a replacement. It was 12 bucks, shipping would cost half the cost of the battery, and it would take them 3-4 weeks to ship another. The original order took 3.5 weeks to be delivered.

Well then, they shouldnt sell it in the first place. Now I'm wondering what kind of reviews it got on that site.

Peal off the cover of the battery. It should say how big the battery actually is. I highly doubt its 3500. But you never know

I was about to say this. You more or less likely got a fake Chinese battery that claims it's "..." mAh, but in reality it's significantly less. I've seen this happen too many times on the EVO 3D forums.

Theres no label, the writing is printed on.

This is it here.

Here is one of the reviews: Looks like the same story as yours.
2.0 out of 5 stars Lasts same as the original, January 19, 2012
By Sunny - See all my reviewsThis review is from: GTMax High Capacity Extended Replacement Battery (3500mAh) for Samsung T-Mobile Hercules SGH-T989 (Package include a Neck Strap) (Wireless Phone Accessory)
I was excited to get this battery thinking that it would atleast give me one and half times more backup than the original. However, the backup i'm getting is not any better than the original battery. I will see for a couple of more days and if it is still same, i'll move back to the original battery and keep this one as back up. Help other customers find the most helpful reviews
Was this review helpful to you? Yes No Report abuse

Most cheaper priced batteries out there engage in false advertising. Don't believe the mah numbers you see even if they are the same as the stock oem battery. Its cheap for a reason just like the fake micro sd/flash drives for sale at Ebay. There are also shady vendors in Amazon who pump up their own ratings by leaving positive reviews especially the "ProdiCell" cell phone battery brand. With the exception of Seido and Muge, I would only stick with Samsung oem batteries. The Samsung Nexus extended oem 2100 mah battery is really good for $24.99 (50% off 49.99 at the Verizon store). I do see the extra 14% life. I went 34 hours the other day on stock 2.3.6 before my phone died. I actually ran 30mins of video at the end to run out the charge.

Ill try this out with synergy, since faux i heard was a drainer, and if no luck ill stick my stock battery in and continue to use my ballistic case. Ill also give it one more day.
Never tried an alternative battery till this one, and if im gonna go bulky again ill get that 3900 mah mugen, since that appears to be the real deal.

Extended battery longevity practices

I ordered the HTC 2150mAh Li-Polymer extended battery and door from HTCpedia. What tips do you have to ensure that I get the most out of the battery? Is there a particular charging process you go through when you get a new battery? The battery was expensive and I want to make sure I take good care of it.

Fully charge, then use. It may take a few cycles before you see optimum battery performance but you don't need to "condition" the battery. Lithium ion batteries do not need to be fully discharged/recharged, in fact if this is done frequently it can hurt the battery.
You can do a google search if you want a more in-depth explanation.

Fully charge battery,then while the phone is still plugged in, power phone off - leaving it plugged in, then you'll notice the LED will turn red again. The phone will charge for about another half hour or so - this will give you a true full charge.
The OS on the phone will think it has a full charge, thus cutting it off before it is fully charged.

I was told they weren't available through Verizon yet. HTCpedia has an awesome return policy, so I think I'll send it back and get it through Verizon. I could really use that extra cash.

Just got mine from Verizon today and my company gets 25% off accessories, so it cost me $48 w/tax. I got free overnight shipping by using promo code: freeovernt
Still charging...
After only one full drain and recharge i've had over 21 hours of battery life. i've been using it like crazy for the last 3 hours to drain it again. I think i could easily get a day and half out of this bad boy. Well worth the added bulkiness i might add.

I'm using my stock rom still (havent taken the rom plunge yet, mostly cause I have everything like i want it right now).
I flashed the hydra undervolt/overclock kernel (hydra_ocuv_ov2_n_v07_signed) and have setcpu set at min 128 and max around 800 (i change it to 1000 or so when i need the extra umph and not trying to save battery as much).
Also I have the Verizon 2150 mah extended battery.
Currently with medium usage (both using the internet, barcode scanner, playing a couple songs here and there, send a couple text messages, 1+ hours a day on the phone, playing with the phone on wifi a bit), im getting over 48 hours usage.
Last time on the charger was yesterday morning at 10:30am. Its almost 11 pm and im at 50% right now. I dont have gmail doing an email checks right now at all (i check it manually once in a while), and I only turn on 3g as needed.

OEM1500 v Seidio1750 v Mugen1800?

Which battery do you prefer?
According to http://batteryboss.org/ the OEM 1500mAh is the best.
I just wanted to see what the users have to say, I am assuming I will get a responses of each person claiming theirs is great. I am looking for someone who may has had one or two of these and their opinion.
Either way just looking for opinions before I buy...
Wow I got all mixed up.
I was thinking of "HTC Incredible 2150mAh Extended battery"
- post edited.
I'm guessing you're looking for a battery that doesn't increase bulk?
The options available aren't much better than stock sadly :/
Depending how old your current battery is and how much stress you've put on it by draining all the way or bump charging, getting any new battery you may see better battery life. Still would suggest the HTC Extended, but just my opinion
I have the Seidio battery and of course the stock battery. I can't imagine how they could say the stock battery is best. My Seidio greatly outperforms stock, and does so consistently. I can usually get between ten and twelve hours out of it under moderate to heavy use. As for the other battery you mentioned, I can't comment on it since I have no experience. I'm curious to hear what others have to say though. I've never heard of it but I'm always looking to squeeze a little more quality time from my phone. Anyway, I wont say mine is best but, I can say, honestly, that you wouldn't be disappointed with the purchase.
Edit: With regards to cases, Seidio's Innocase line is excellent. They slide on end to end for easier battery changes and they're 1mm thin but very solid. And +1 on the custom kernel. SETCPU as well (if you're rooted.)

They are saying OEM incredible batter is better, they are saying the OEM Evo battery is better. Inc comes with 1300mAh, Evo comes with 1500mAh.
They also said the 1750 only uses 79% of its capacity, meaning your only getting 1382mAh...
But if your happy that is good to know, improvement from current stock battery.

I have to wonder if they bump charged any of the tested batteries for the Dinc. I haven't read the article yet but I will when I get a Chance. But, as you may know, a known issue with the Dinc is its inability to fully charge its batteries without unplugging, powering off, then plugging in again. If not, you're battery will truly only have about 80% charge.
Sent from my ADR6300 using XDA App
You shouldn't bump charge, it kills the battery quickly.
They have that feature to keep the battery more stable and last longer.
It charges it to ~90% (you'll see it drop from 100% to around 90% very quickly once you first unplug it) and cuts off at ~10% (when phone shows 0%).
It's how Li-Ion batteries work and you really shouldn't manipulate it so you get more unless you are wanting to buy a new battery every month.
If you keep doing that you will start getting worse performance bump charging than people who have been regularly charging for much longer than you have been bumping.
Just a suggestion though.

Thanks for the info POQbum. I wasn't aware of that. After reading so much about how the Dinc needed to be bump charged, I guess I just assumed it was ok and didn't have negative effects on the battery. But I do have to say, I've been charging that way since September without any noticeable issues. Battery life is still great and haven't replaced any batteries. If anything, my battery life seems to have improved. For the first time today, i was able to go ten hours on my stock 1300. Maybe its CM7. Anyway, I'm in no way trying to say you're wrong though because what you say makes sense. I'm simply sharing my own personal experience with these batteries.

Hated my Seidio battery. For the price its no where near worth the gain. The eBay OEM 1500mah by bidallies for $14... worth every penny. Love that battery.
Went through three Seidio batteries cause I assumed I had faulty ones but I barely got through the day. My TP2 battery lasts from 6am til 10pm or 11pm depending on usage.

That batteryboss link is still flying? The 1750 is definately a step above the stock. Not sure what that dude has against seidio but keep in mind he is one guy who basically ran one test on one battery iirc. My seidio 3500 will take some serious abuse and still last a day or 2. The 1750 was way way better than stock...I'd say a good 3 hours or so better for me. Anyway the best investment i made was a cheap ebay wall charger so I can just swap in any battery that fits my needs for the day...I switch between stock, cheap knockoffs, the HTC 2100 and the seidio 3500 now, sold the 1750.

Sieidio Battery 1750mAh Extended Battery Review

I purchased the Sieidio Battery 1750mAh on Amazon about a month ago. This battery is not worth the money at all. If you want an extra battery then I suggest buying an OEM battery.
I might be wrong but I think this battery actually goes down faster than the one that came with the phone. My biggest problem with this battery is that it does not fit properly in the phone. It can just be set down or place in my pocket and that is enough to make the phone.
DON'T wast you money on this battery

I got two 1800mAh batteries for about $30, and experienced the same thing. After awhile though, I realized that you have to do a few things to get better battery life.
1) Charge the battery to full while the phone is on.
2) Unplug and plug back in to verify that the phone is fully charged (green led)
3) Turn the phone off
4) Unplug, plug in, and wait for a green led
5) Repeat that 5-10 times
6) Then while still plugged in, reboot into Recovery and wipe the battery stats via the advanced menu.
7) Reboot, and use your phone as you normally would.
This may sound like alot, but it really only take about 5 mins. Even after wipe, it will still take about 5 full discharges to reap the better battery life. Hope this helps!
I think its just luck of the draw on aftermarket batteries (the cheap ones at least)
I have heard good and bad on ALL of them.
I got the Chichitec/htcexpress 1800 batteries with charger. Came in the other day and I couldn't be happier. 14 hours on initial charge, that's unheard of for me. On my stock battery I had to keep the phone plugged in most of the day at work just to still have juice by the time I got home. And supposedly these things start acting even better after a few charge cycles.
(Fits with stock battery door too)
But for every person that has a good experience with any of these companies, there's someone else with a horror story.

Could have told you that before you bought it, ratings by aftermarket reputable companies are close and never accurate...if they rate it at 1750, it's probably 1500-1650... The stock is 1500 so yes you wasted your money. Now on the other hand, the 3500 is the best investment anyone could ever make....
It's been proven long ago seidio over rates their batteries. The "1750" is actually just under 1500, so less capacity then the stock battery.
Sent from my PC36100 using XDA Premium App
just terribad in my opinion, gonna stick to my seidio 3500. rather have the size and life than a small size and a measly bump from the 1750mah battery
They rated it less than a 1500 stock battery.
Key with extended batteries is that you actually have to charge them longer than your phone indicates.
Example: I phone said it was fully charged at 3:26am in the morning. Yet it continue to charge until at least 6:45am before it was constant. Granted I am using an SBC kernel but even without, you need to let it charge the night. Don't let the green light fool you. It takes a few extra hours to charge even if the led light is green!
You should just about fully drain your battery and then let it charge overnight. If you aren't on an SBC kernel you may actually want to charge your phone while it's off so that the battery dictates the charge.
You should also wipe your battery stats once the phone is fully charged.
Try that and see if it works for you. I know that I was getting great battery life even on the stock battery. I play "Word With friends" (at least 15 matches running) a lot (at least 15 matches running concurrently) and this game actually drains battery. I still got through the day fine though I also carry a Touch Pro 2 and having the batteries that are the same size allows me to swap when needed.
I have the 2650mah one from sprint and my 3500mah seidio coming in the mail tomorrow. I'll probably write a review for it later. Note, On my 2650mah, it's already on its 12th hour and I was was playing WWF, surfing the web, made several calls and it's still at 77%. I will leave it off the charger tonight and see how it fairs tomorrow.
Good Luck!
I have tested these and if they do last longer then stock, it is only like maybe 20 mins. I have an external charger as well as running the SBC kernel to get a complete charge. I have the sprint 2600 battery as well and love it. Not many cases for it but I have modified a sedio rugged and ballistic to work with it. I let my wife use it for a few days in her evo and had to fight to get it back from her.

Those batteries are a scam..why bother getting a bigger one anyway, not only do you lose Nfc, the stock battery already lasts a whole day easy

it's a POS. i bought a battery from the infuse will be here tomorow and will test it out...yes i know i will get skeptic but if it works i'll be getting 30-40 hours on my phone lol
its not 3500 mah but it is longer than stock
Innocell 3800mAh Super Extended Life Battery
I have used Seido Cells with G1's before and they were still running just like new after 18 months of heavy usage, twice the battery life over stock. The case looked better on the G1 as the back was flush. On one of the phones the case did crack and break after a 3 ft fall. It was a cheap and quick replacement from Amazon, under ten bucks if I remember right.
The one offered is a 3800mah at 69.99 and shipping now.

I really want a better battery too, I'm waiting for ANKER to make one for the t989. I have no idea how people manage to squeeze so many hours from there phones on this stock battery, but I usually go 5-7 hours before it dies. I'm not a heavy user but I do have my screen to 100% all the time. I don't mind carrying spare batteries.

I don't get the problem with the battery, I can watch shows and movies all day at work and still come home with at the worst 40% battery life

LOL - what a job
If people are really concerned about hte battery life etc, just get one of those mobile chargers. They will charge everything from laptops to cell phones...they are called power packs.
first link on google...came up with this. http://www.amazon.com/Energizer-XP4000-Universal-Rechargeable-Power/dp/B0029U2WTG
There is a lot of fraud on these extended battery
Yeah i agree, there is a lot of fraud with the battery packs. Someone should regulate them and make sure that what they advertise is true.

Extended battery??

What is the biggest battery I can get for the Sprint GNex that can stay in the stock battery cover???
I think only the original battery will stay with the stock cover. I have the official extended battery and the increase in thickness isn't really noticeable. I personally feel that it makes the device more uniform.
the biggest battery you can get with stock battery cover is 1750 mAH
I have the sprint version which comes with an 1850mah
You all are false, I have the Anker 2200mAh battery and it uses OEM battery door, as well as requires no modification what so ever. Here. You will lose NFC however.
Here is the samsung version for the GSM version which includes NFC capability!!! check it out here
I have a GSM Nexus for my daily (other one is for work) and I use this Mugen battery. Yeah it's pricey but I had eBay bucks collecting I practically go it for free. I really think it works better than the OEM Samsung battery. I can usually get easily 2 days running Franco's 217 JB kernel OC'd to 1512 or w/e it is.
I found this http://www.amazon.com/Ecell-FEIPUSI-2200MAH-CAPACITY-BATTERY/dp/B0086KT4SA
I don't know if it will work with my sprint GNex though???

I'd only use batteries that say its compatible with your phone's model number. i9250 is the GSM version.

I'd agree with xreflection. Make sure it clearly states it's for the exact model of your phone. Also, I've never heard of Ecell, nor have I ever seen a thread about an Ecell battery, therefore I'm sure it's not really a 2200mAh battery, just something rebadged as a 2200mAh battery.
I would stick to OEM, Anker, Mugen, Hyperion, Qcell and Galileo. I've had nothing but fantastic results from those companies in the past. Can anyone else add any reliable battery manufactures they've had positive results with?
I would be weary of the mAH claims of various unknown-brand batteries. The capacity of a lithium ion cells is in direct proportion to size. So if one battery is claiming to be the same dimensions as another but has an extra 200mAH then something is up. All of the batteries use the same technology so there is no magic here. Other than what little they can do on the circuit board. It mostly comes down to the fact that most people can't measure the actual capacity of the cell.
I trust the samsung extended battery and it actually improves the feel of the phone. I think that's about the best you can do.
Oherwise you're looking at really increasing the size of the phone and that's down to your personal taste. For my hands I actually prefer the bigger phone and enjoy charging it every three days with the 3800mAH whale battery.

I've also had great experience with those battery manufactures. Also, I just received a battery from Amazon called Onite (only 3500mah I could find that works with NFC and was for the GSM version). when I get the phone tomorrow, I will test her out and write again giving it a review.

I was always interested in the company Onite, especially for my Galaxy Note. I never pulled the trigger because I couldn't find anyone that had any information about their products. Please do report back on how the battery performs!

Yeah, I know. I only saw one review on Amazon and I couldn't really tell if it was real or not. But, hey for a price of $12.80 why not take a chance? Hey, if the battery explodes I will make sure to have T-Mobile phone insurance and hopefully a warranty with the phone! With my HTC Evo 4G, I bought all my batteries from eBay first but then after I discovered some overheating issues I started buying batteries from Gorillagadgets.com. Its a shame they don't have any accessories for the Gnex. With my Evo though I got as much as 3 days out of one charge with a 3500mah battery and the perfect rom and kernel combo. Hopefully I'll be able to have at least 1 1/2 with Jelly Bean. We will see tomorrow.

Hey, just a quick update! I received my phone as well as my Onite battery today (hoping it wasn't going to explode!) and I haven't even opened up the OEM battery yet! I popped in my sim and battery immediately and began setting it up. I'd say the battery was at about 55% (if I remember correctly, around there) when I received it at 5:30 and it just died about 15-20 minutes ago so it lasted around 5-5 1/2 hours (of heavy usage mind you, I was playing with it the entire time, I think I put it down once) and I hadn't even charged it yet! With my experience with extended batteries I know its good to cycle them first and let them die the whole way, then charge them up the entire way a few times to get 'em warmed up so thats what I'm doing now. I'll update again tomorrow when I use it for an entire day.

I just got my Galaxy Nexus yesterday and was also looking at an extended battery. I'm not keen on anything exploding so I'm a bit wear and looking forward to hearing about your experience.
Do you have any images of what your phone looks like with the Onite battery + cover attached?
Hey. Yeah it will be hard to determine until next week what the battery really does in regular use, because I just got my wisdom teeth removed so I'm just running on WiFi all day. I've been running it non stop since around 10 and its at 77% now so we'll see. As for the picture tbh it can't do it justice. The phone is already thin and light enough and the battery (imho) makes it feel better in my hands and adds virtually no excess weight.

Oh and by the way, I charged it overnight and it hasn't even overheated NFC works on it as well! Its a good battery for $12

The Onite battery looks very promising. Does anyone know a shop, which ships the item to Germany?
Hm I don't know a place but depending on how long you can wait aber ich komme Ende September nach deutschland und kanns mitbringen ^_^

Well guys. Its 7:35 and its been on battery for 8 hrs and I still have 12% left! This was only the 1st charge so it only gets better from here!

Oh yeah! And to comment on the back cover that comes with the Onite battery: its the same color as the gray on the back of the phone and it doesn't feel like the usual cheap covers that has the color that rubs off after normal use.
