Hey guys I just saw a 3500mAh battery for SGS2 on ebay. Is it safe to use such battery? I mean it won't harm the phone, will it? :O
Probably won't harm the phone, no.
I bought a 3500mAh obscurely branded Chinese battery in mid-December. Tried it out for almost two weeks, a bunch of charge/discharge cycles & estimated its real capacity was around 1900mAh. It also used to heat up a lot on recharge (mid-high 40's Celsius, which isn't normal when the phone isn't being used whilst charging).
I took it back, got a refund & bought an original Samsung 2000mAh battery. Hasn't missed a beat, is obviously close to its advertised capacity given I get around 20% more use out of a charge than I do with a 1600mAh battery.
Obviously your mileage may vary if you buy one of these (you might have a better experience than I did), just thought I'd let you know about my experience.

Well i heard that their batteries exploded in their phones......so be careful.....better pay for a better one instead of having a chance to ruin your expensive phone.

I have one of those I got from DealExtreme and it is great. It lasts 2x longer than the original Samsung battery.
I take care not to swap them often, because I am afraid that this action might damage the original cover, eventually breaking it.
Battery Life
I am still using the 1650 mAh battery (stock) for my S2.
I am really facing some battery issues. Its charging almost all day !
Yes I am using 3G all day and WiFi HotSpot too. But use wifi at home. Thats when I get good battery life. Any better way to conserve some battery ?
Any tips might help
Thanks
Got mine a few days ago from eBay and its been fine so far. It last more than 2x the regular battery. Phone does not heat up or anything strange..

well i an getting with the original battery 24H of usage.
with the 3500mah i am getting 60H of usage... so my 3500 is truly 3500mah!
the language is hebrew.
i use congnition rom 1.51 and siyah kernel.
So, where can I see a trustful review on batteries for SGS2? What is the most extended one?
It's really frustrating that my current stock battery is only enough for 2 hd video view (4-5 hours).
Also, the higher the mAh value the more battery lifetime is, right?
I would really want to buy 3500 mAh, but it costs so little.
And the official Samsung variant that offers the longest lifetime of a battery for SGS2 is this one, maybe Mugen 3500 mAh is the best choice out there?

What is the model name of the battery? Is it being overheated in comparison to stock one?
why should it overheat?
it is lithium ... same same
Yes, it's special lithium from China extracted under full moon and blessed by a thousand virgins
Really now, if it was possible to manufacture a battery having more than double the capacity of the stock battery while taking up the same volume, don't you think the megacorporate Samsung would buy that technology immediately in order to use it themselves ? "Too cheap to be true" is valid even here; most knock-off batteries either are fake ("9999 mAH SUPER EXTRA" sticker over the original rating), or will degrade quickly in time leaving you with a dud.
Since there are already fake electronic components...
... why not fake and cheap batteries too, certainly seems to be a high demand for them.
a. it is not the same volume! in is twice as much as the original.
b. the i9100 has a circuit that allows a slow stable charge rate so i dont think it will damage the battery.
As well as being made of inferior materials, not being subjected to the same QC, not having the fuel gauge chip present in original Samsung batteries, you pretty much get what you pay for.
My advice would be to avoid non-original batteries altogether, and given a 2000mAh original battery will cost around the same as one of these 3000mAh+ batteries with all their problems & poor life, it's a no brainer.
Stick with Samsung batteries.
fuel gauge chip?
i would like to see that chip in an any cellphone battery please.
If you're not aware of/don't know about the fuel gauge chip in original SGS2 batteries, you've probably been living under a rock since the phone was released

well i think that you misunderstood the meaning fuel gauge.
there is no chip in the battery that is in charge of the fuel gauge.
furthermore there is no use of recalibrating the battery in out i9100 model.
all you gave me is a link you Google...
please... show me that chip! i would like to learn something new about lithium batteries..
Plz can you Possible link topic of the battery

What about the other question that you chose to ignore, regarding the battery's model that you mentioned.
thanks for the info guys,
cuz I need a battery really disparately cuz I use so much data and sync :'(
I couldn't find something really reliable feedback from viewers, and i'm trying to find something with good quality as well!
guess i have to search further!

You have a point mate! Thanks
I've used my Galaxy Nexus for six months without using a secondary battery. At first I bought the extended battery with extended battery cover, but not only did that make my phone too 'thick', it also seemed that Galaxy Nexus is unable to know which battery is being used, so the battery life seemed incorrect when using the extended battery.
I think this has something to do with the battery info memory that the phone stores.
So I ended up buying a second battery, a replacement battery that is exactly the same as the one I originally have in my Nexus.
But since batteries are still different and are bound to perform differently, I wonder how to manage it correctly? Do I always have to drain the phone completely empty before switching batteries and charging the battery with a separate charging dock? I am worried that the phone considers performance of my battery A as the same as battery B, thus in time ending up with lesser battery life on both due to the confusion.
Are there any tips I should know? I need to use replacement batteries since at times I'm on an extended trips where I might not have the ability to charge the phone, but need to use the phone one way or another.
Thanks!
Ah..... I bought some batteries from Amazon. Cheap, like 20 bucks. They are charged, in my bag, if I run out of juice, I switch and start charging the other one. I still have a 3rd that I've never had to use. Hell I hardly use the 2nd one.
All the other stuff you mentioned, I guess I just don't care about all that. I just know they can hold a charge for quite a while. And that helps me when I need it.

These are Li-ion batteries.. DO NOT DRAIN THEM ALL THE WAY DOWN!
**This shortens the life of the battery**
It is better to charge them whenever you feel like it - these batteries and really almost all phone / laptop batteries these days prefers to be charged in shorter cycles and they also do not need to be charged all the way either - IE lithium ion batteries do not have a memory and do not need to be drained and charged fully.
These ideas come for the ancient Ni-Cad batteries famous in AA rechargeable and cordless phone and really old phones / laptops..
Chances are if your device is less than 5 years old it has Li-Ion batteries and the old school thought will actually shorten the battery life
Battery life meaning the amount of power it holds and the number of charge cycles...

You CAN drain them down, as much as the phone allows you. Only deep discharge will harm/kill them.

You cannot drain battery completely empty with a phone. Phone itself will not allow that to happen. Well, it is technically possible, but you need to do a lot more than just drain it until phone shuts down to make it happen.
My problem is that the phone stores information about battery. But if I use two different batteries (despite being the same type and capacity), during battery switches it will not know the battery life of the second battery and can be wrong (as it guesses it based on first battery). People usually delete batterystats file to reset this information, but that sounds pointless to do after every battery switch.
I guess I'll just discharge one battery to about 50% and then store it for just-in-case purposes.

Just a quick link to help out, if you want more info you'll have to Google it yourself
You can use 2 different size batteries without decreasing their usable life per charge.

Anybody can think of a battery that has more mah but same physical size as the one this device currently rocks? Would be awesome if we could fit the battery of the latest moto device but I believe that one is thinner.
Sent from my ONEPLUS A3000 using XDA-Developers mobile app
Swapping batteries in from other devices is a bad idea... Not only are they not likely to fit inside the case (check out some teardowns of the OP3) but the dash charge is calibrated for your battery, not for some other battery. Putting in a different capacity battery can cause some pretty hefty damage... Do some research into battery tech, these batteries generally have as much power capacity as physically possible based on the battery chemistry, you won't find a (legit) battery with a higher capacity of the same dimensions.
Remember those hoverboards that seemed to spontaneously ignite at random? more often than not it was due to poor wiring, faulty batteries, or being charged / discharged at a rate greater than what was designed for.
Give it a couple weeks / months I'm sure there will be a battery case developed for the OP3 but with how quickly this phone charges its designed to be topped up semi-regularly instead of charged once and run all day (or multiple days).
I've heard people say they are on transit for long periods of time and don't have access to a outlet, try looking for a battery bank to charge your phone if you feel the need...
And yeah, I wish they made the phone just a LITTLE thicker and put a larger battery in it. Really, I don't need a phone thin as a pancake, it could have been the same size as the OP2, ONE extra millimeter could fit more power, removed the silly "camera bump", and not impacted feel or ergonomics in any meaningful way.
Got 2 new batteries and I want to keep them for a while, so I have a few questions:
1. Is the OEM fast-charge charger and cable okay to use every day, or will it degrade the battery faster than a slower/regular speed charger/cable?
2. Since I have 2 batteries now, which is the best way to charge them both up? charge 1 in the phone, then swap and charge the other in the phone? Or buy a battery charger (and if so, which one)?
3. Any other helps regarding the chargers and/or cables?Thank you for your help.
Faster charging will always generate more heat and put more stress on the battery, so slower charging would be better for a battery's lifespan, but I don't think you'll see a huge difference within two years.
By far the fastest way to keep going is having the second battery charged in an external battery charger and then swap when the other battery gets low, followed by charging the low battery in the external charger. Doing it this way also puts the least wear-and-tear on the phone's charging port since you'll rarely use it. I use LG's OEM external battery charging cradle (BCK-5200), but it may be hard to find nowadays. There's currently a used one up for sale in an auction by an American seller on eBay, and there are new ones from a South Korean seller for a higher fixed price. I wouldn't pay more than $25 for one. As for charging time, for me, it takes about 4 hours to charge my MaxxxJuice 4100 mAh batteries from ~5–10% to full. External chargers do not fast-charge, so you'll never put too much stress on the battery that way. Of course, swapping may not be for everyone as it may be inconvenient to take a case off and put it back on.
Unlike the older microUSB cables, bad USB Type-C cables that are not built to certain specifications can draw higher currents and destroy the devices they are charging. A few years ago, a Google engineer reviewed lots of USB-C cables on Amazon to give his view on those. If you need a third-party cable, make sure you get one from a reputable source with good reviews. My preferred USB cable is Anker's Powerline+ due to their extra strength/thickness, and I don't need much flexibility/twistability in my cables. Also, I like how the USB-C end connector is made of one single piece where you don't see any connecting lines around the middle (you can see an example here).
Other thoughts:
As long as there is a supply of extra batteries around and you can afford to buy them when the time comes, then you shouldn't worry much about how you charge your phone. In my opinion, that is one of the main selling points of having a hand-removable battery. I imagine a paranoid person on a phone with a sealed battery would be trying to keep the battery level between 40 and 80% at all times. So really, the only thing to worry about is having a decent USB-C cable and making sure the phone's charging port is clean and not worn out.
In case you are really interested on my detailed charging habits and related things on my V20, I discussed them while reviewing my batteries a while back on the V20 Subreddit.
Thanks!

On that Subreddit, you mentioned you cycled a couple batteries. Did you have to do the whole fully charge and fully drain thing each time you switched to the new battery, or just when you first bought the batteries?
Would like to know the answer to ^this^ as well.

No, I only did the full cycle with the first battery three times, and that was it. The only reason to do that is for the Android software of the phone to get a better sense of your battery level. Of course, it won't be as accurate the longer you go swapping between batteries as undoubtedly they will differ a bit in capacity over time. But fully running down and then fully charging a battery isn't good for its lifespan if you do it too often. The only other times you'd have to really repeat the calibration is when switching to a battery with a different capacity or switching ROMs / doing a factory reset.

Most likely yes. I imagine most of these 4000–4300 mAh Lithium polymer batteries that started popping up this year are very similar, and some may just be rebranded from the same common factory source. Barring a defective battery, if the two batteries had a significant difference in capacity, you could see things like early shutdowns on the smaller capacity one or being stuck at a low percentage for an unusually long amount of time on the larger capacity one.
Great info.
So it looks like all other batteries on hand should not be put into rotation with the higher capacity batteries to avoid inaccurate readings in Android.

Pretty much this. I suppose one could try keeping separate copies of the batterystats.bin file from /data/system when rooted and swap them alongside the different batteries. But that sounds like too much of a pain to deal with, even if it works.

Just to add to this, I found your pics @C D for the charging instructions and there's a note about using 3200mah batteries along with the 4100mah batteries.

Does that mean that if you switch between the batteries, they'll both last as long as they should (the 4100 longer time than the orig. 3200), but the system's percent will be wrong?
My understanding is that if you calibrate the phone to recognize the full 4100mah and then use a 3200mah battery, it will shut down early (but still use the full 3200mah).
Correct. They are warning you that swapping between batteries of significantly different capacities will throw off the accuracy of the phone's battery percentage indicator at all times, especially at the high and low percent values (so an early shutdown can happen when the smaller capacity battery is used). Of course, this won't affect either battery's true capacity.
I'd pay good money for a system that can correctly handle different battery capacities of any amount, but we all know where the future of hand-removable batteries has been heading for the last 3–4 years.
Does anyone charge their phone ONLY to 80 % or so?
If so, what apps do you use to limit this? Any other tips/advice?

I use AccuBattery and it has a notification sound that plays when you hit the target charge percentage, but it's still up to you to remove the phone from the charger or else it continues charging to 100%.
Since our phones have replaceable batteries, I haven't made any special effort to take care of them. I have a pair of May '17 OEM 3200 mAh batteries that are going to get switched out for a pair of new 4100+ mAh Li-Po batteries once I get my second V20 set up. Every charger I use is QuickCharge 3.0 certified except for USB on my PCs and my Pioneer Android Auto headunit USB connection in one car. The vast majority of the time, I charge via QC 3.0. Pretty much the only time I let the battery charge via PC USB is when I actually need to transfer files between the phone and computer.
Before my phone started having issues in the past month with a phantom power drain, I would let the phone charge from 30-40% to 80-90% and then remove it from the charger at night before going to sleep. In the last half year as the batteries have aged, I've let it get up to between 90-95% before unplugging. For the past month, I've been charging the phone four times a day from 40-100% to combat the power drain issue, but that comes with knowing that I don't care about these old batteries or the state of the firmware on this first V20 anymore.
As for when I swapped the two batteries I have, that entirely depended on when I actually ran one down so far that I needed a 0-100% battery swap, which could be months at a time and usually happened while on vacation or away from a charging source for a longer period of time than what my usual home/car/work routine allows.
Hi guys.. I'm thinking about buying this battery case for the mate 20X. It says it has a battery capacity of 6000 mah. Does this mean that this capacity is separate from the 5000 mah the phone has, so that I get a combined 11000 mah?
Has anyone here bought it? Is it worth buying?

Just some helpful advice from a recovered extended battery case addict. In the early days when phones didn't have quick charge and we're about 25-50% smaller, I always bought my phones based on the support of manufacturers making extended battery cases for it. As the phone market matured, batteries became bigger and locked in, I noticed that my power consumption was less likely to hit the max of the stock battery. The weights of the phones increased as well and I noticed a chronic pain on my pinky. This combined with the fact that the extended battery cases didn't have quick charge, rapid charge, super charge, it whatever "special" charge came with the phone, as well as a key missing feature of charge passthrough, caused me to drop the extended battery madness. I expect you to come to this conclusion on your own, because like me, you won't be convinced of extended battery cases being a bad joke until you see it for yourself. Make sure there is a good return policy.

Hi techronico,
Appreciate the reply. As far as quick charge goes that will damage the battery in the case the same way it can damage the battery in the phone. This is why I have a slow charger to charge my phone healthily instead of risking permanently frying the phone's battery which will shorten its life. I'm no fan of quick charge.
Regarding pass-through the seller confirms that the power case is equipped with heat, overpower and temp protections. What do you think?
Just to be sure the power case doesnt degrade the phone battery do you think its best to charge the phone case and phone separately and not connected together?
Looking forward to your reply.
I would never spend money on anything like that since I can get 2 days on a single charge on my 20X. All the new phones now use LiPo batteries (the same cell type used in Tesla cars) and have no problems with quick charging and don't exhibit memory as it's predecessor battery types used to have.

Hi ben,
I'm not talking about quick charging. I love slow charging.
Anyway I get 3 days from my 20X. The problem is when I have 30% left it starts to drain like crazy. Thats the reason for wanting the battery case.
Did you get the battery case in the end? They are available very cheaply now from Aliexpress. I don't really have a problem with battery life but am thinking it might be a nice gadget to have
