I've made my old phone last by buying replacement batteries. This is handy as when I have a busy day (ie. traveling, vacation) where I take lots of pics, video, use navigation, my battery will last about half the day. Then I switch batteries and it gets me through the rest of the day.
The problem is that at night, I want to charge up both batteries so they are ready to go in the morning. Unfortunately, the phone is the charger so I only have one. I usually have to wait for one battery to fully charge and switch to the other one before going to bed to ensure I have two good ones in the morning.
Are there any external battery chargers I can buy so I can charge two at once?
There are plenty of USB batteries that people sell, but these are typically more bulky (and you have to carry a cable) than carrying around a second phone battery. They USB battery also needs to be connected the phone for a long time to charge it.
I have one similar to this, seems to work fine but the batteries are hit or miss.

For the past couple of days, my phone's battery life has been pathetic. I kept it in my pocket for around 7 hours, and when I checked it, the battery almost completely out of juice.
Welcome to the club.
really
im having the same problem
Likewise, there seems to be little capable besides having a charger around, or maybe an extended battery. I put my charger in my pocket because I have access to an outlet or PC (for USB charger) almost always.
I also usually have my car adapter, just in case. I still want an extended battery however. They give this thing NO juice for so much power

That is the link to the extended battery and cover that I use. It lasts a heck of a lot longer but with most extended batteries you have to give something to get something.
[Q] How to charge battery properly on first time usage & is a converter adapter okay?
Hey guys. I have two questions for ya.
There seems to be various opinions on how to properly charge the battery when you first get the S2.
I seem to here two ways:
1) Charge the battery fully (maybe a good 8 hours? Anyone have a good value?) BEFORE first usage. Then you can go ahead and use it. <--- I was taught this way back the early millenium with all the new fancy cell phones.
OR
2) I assume there is probably going to be somewhere between 50-80% of battery life before you even put the battery into the phone. Thus, one should use up the battery until it drains completely. Then recharge it back up to full again. And vice versa.
Which is the correct method of choice as far as preserving battery life? Does it even matter?
My second question deals with whether an adapter for the battery charger would be okay. Like many of those who live in the states, we have to import the S2. I bought mine from Expansys-USA, which gave me a UK/European model adapter and then a generic converter (for converting UK/Europe to US/North America). Anyone know if this is okay for the phone or battery? It seems like there would be an "extra barrier" to prevent the phone from charging 100% accurately or properly. I do not know too much about electrical engineering, but it just feels like the Europe-to-NA adapter is acting as a sandwich between the phone and the outlet.
Should I go as far as buying an adapter from Canada (if they have one available) to ensure maximum charging compatibility?
I have always charged my new phones for 24 hours (roughly) then used it until it went down to 10~15%, then finally do a four+ hours charge (doubling the time it took to reach full charge). After that I charged/discharged as needed. Phone batteries have moved on since my first phone, but I still use this method.
It is not really proof but a colleague bought the same phone as me at the same time a few years ago. I did my usual routine, they never bothered (even though I told them). After about a year their phone wasn't holding the charge as well as mine (for roughly the same amount of usage).
The adaptor is rated from 100 through to 240V and 50/60Hz. So basically it works (nearly) anywhere you have mains electricity. There is no effect on charging. My old HTC HD2 charged fine when I was on holiday in the USA. So no worries.
Given most (all?) phones actually cease charging the battery completely once it reaches full charge, I don't get why they recommend you "charge" it for some inordinate amount of time the first time.
Hence, there seems to be 2 schools of thoughts here. One for charging and one against charging upon initial usage. Hmm...
On another note, according to this 2000mAh battery pack located on eBay: http://rover.ebay.com/rover/1/711-5...at%3DSee-All-Categories%26_fvi%3D1&_rdc=1
"Initially new batteries must be charged for 14 - 16 hours continuously. All batteries require a "break-in" period, so don't be panic if your battery doesn't hold a full charge right away. For the first 3 - 5 cycles, please make sure to charge the battery fully and drain it fully before recharging. This will properly condition the battery and will ensure that it will operate at its maximum capacity."
Not sure what your guys thoughts are, but this sounds like a plan to follow for the paranoid users like me, eh?

I just got these from Amazon and the charger that it came with is JUNK!
It has sliding pins and no instructions on how to charge the batteries.
I used the samsung battery charger to charge it, when the charger saids its charged, I put in the 1st battery and saw that it was only 89% on the phone. I hope this means that the samsung battery charger will only charge up to 1650mAh and there is extra juice on these Ankers.
I will continue to test it out and will update.
I bought these too. To use the charger, slide the pins to the right so that they line up with the copper contacts labeled + and -. I think when you have the contacts on the top right, it is the right most, and then second from the left. Slide the bottom of the charter down and stick the battery in with the pine touching those 2 contacts.
Now, that being said, the light indicated on my charger stopped working after 2 days, so I just leave them in overnight. Also, you can't charge them in the att phone or you get a boot loop. But the batteries themselves seem to last.

How is these batteries working out for you?
It seems WAY too complicated to use the charger which came with it. Does it matter if the left pin is connected to + or - as I can easily flip the battery around.
I am now charging it with the charger which I got with the GTMax batteries, its slow (Output 4.2V 350mA), but it seems to be charging it to 100% instead of the battery charger from Samsung. (Output: 4.2V 400mA 600mA) (89% for some reason, I have not tried again)
I am getting decent battery life out of it as of now, but have not try it enough for a good review. The product does say that the battery will perform better after 4 charges. Since I have 2 of these, they are lasting around 30 hours each,. its taking me time to cycle through it. Is it reallt 1900mA which should last around 15% better than the OEMs.
I will post my findings when I have tested this enough.
I dont know the rest of you, but I like not charging with the phone charger at all. Its takes seconds to pop in a new battery and I am good for another 20-30hours depeding of the battery. No time off for my phone Also, I dont want to change the backing for extending battery which diminished the thin aspects of this phone. (I just carry a spare and it will for SURE last at least 24 with heavy use; greater than 6 hours of screen time if not more)

30 HOURS!!!! Wow. I am lucky if I get 8 out of these or the stock battery. Are you using bluetooth?

It does matter. The right hand pin (when you are looking at the front of the charger) is +.
When you hold the Anker battery face forwards and upright, you can see the +- markings on the battery. This is the direction to use in the charger. I have not yet bought (or seen) the adapter from Seidio which is supposed to their charger work for this sized battery.
I was originally getting 12 hours until 0% battery left. After I shut down all the background syncs, wirless, gps, bluetooth..etc, and installed juiceDefender, I was able to get to about 20 hours with the OEMs. That means, 20hrs with minimal use and it would be dead/unusable at that point.
Then I follow the rooting and de-bloating the i777 and it gets my phone up to 30 hours until dead with normal use. This is around 3 hours of screen time. It would be great if I can ge to about 40 hours..
After a week of use, these batteries seems to last. I think they are as good as the OEMs or maybe 5-10% better. I have also notice that the weight on these ankers are a bit heavier too. Not sure if that means it contains more juice or not.
I have JUNKed the charger that came with it, as its just not user friendly. I been using the GTMax wall charger and its been fine. It take like 6-8 hours to completely charge. (I have not tried again with the Samsung wall charger as the 1st time only charges it up to 89%)
If you are like me, who don't like to chain the phone to the wall and prefer to swap out batteries, then these are good. I hope it there are a lot of cycles life with them.
I travel a lot and with every swap, I get abother 30 hours of moderate use (3 hours of screen time). Under heavy use, I get about 20 hours (4+ hours on wifi)
Just gonna review some of the accessories I have used and what i think about 'em
First up is the 3500mAH extended battery by HHI
This battery came in at a cost of $9.99 with free Shipping! It showed up with an 80% charge which is in the acceptable range of where they like to sit. The battery performs just as one would expect it too. I am currently running MeanRom, and can easily get 16-20 hours of use with some really heavy gaming. However I recently went on a vacation and wanted to run the battery through a couple different variations of "discharging". So with the phone in Airplane mode(no radios connected) and very little use i easily can get a week out of the phone without charging. Again this is without any radios on, not connecting to anything.The stock battery cant touch these numbers. i would be lucky to get a full day out of the stock battery with no gaming and normal use.I didn't do a sticker pull to run the numbers. So I'm taking HHI's word on the 3500mAH being just that.
To conclude on this battery the $10 investment turned out to be a good choice, although it might not be a seidio or something it does more than i expected it to do. I will continue to use this battery till I get rid of the phone. The battery can be found here.
To continue on the batteries,
I also bought some of the Galilio "2000mAH" batteries, I got 3 of them with a wall charger for $13.99 on ebay, as reviewed by many others.
This is my experience with them. So they showed up in the mail and upon opening them i discovered one of the batteries look like it got dropped or skipped accross the cement, im not sure what happened, but who is gonna put a messed up battery in their phone.. So i really only got 2 batteries. I brought it up to the seller he offered me $3.00 back, it wasn't worth my time even dealing with that any further at this point. Anyways the batteries Are nice little backup batteries i take with me on trips.They make for easy backup batteries. The batteries have been suspected to be somewhere along the lines of 1000-1200mAH. I would have to agree, even with no testing with any type of tool, besides my phone. They last a most couple of hours. The wall charger that came with them actually surprised me. Everyone was reporting that it may overcharge your stock battery, which can cause some issues. This charger(as pictured below) will charge the Galilio batteries to 100% with no problems. I put my stock HTC battery into the wall charger and with repeated attempts the charger will not charge the battery past 85% even when i left it on the wall charger for 2 days. I do believe that the stock HtC charger that came with the phone gives the batteries a "better" charge, but the wall charger seems to not charge the batteries past a safe range as everyone seems to be reporting as a possible issue. My issue is it doesn't charge it well enough.
I've attached some pictures of the battery results and of the batteries.
Reserved for more... case reviews coming up next
i got the 3500 mAh from HHI. great battery, even better price.
Yea that battery is awesome!

Going to try this battery out. Thanks for the review.
The 85% is charge limit is what a cheap charger do,
The "charger" that come with the phone is simply a power supply, the charging circuit is actually "built in" to the phone. You can connect the OEM HTC charger/power supply into one of those cheap aftermarket dock that charge a 2nd battery and it will never charge the battery past 85% either.
To make it short and sweet
There's 2 stage of Li-ion charging
1) charge to 4.2v at constant current which is 85% when it first reach/near 4.2v
2) saturation charge, once the battery reach 4.2v, continue charging but at gradually reducing current until it reach about 3% of default charge current
Cheap charger have a simple/cheap circuit and cannot do stage 2 charging, where the charging circuit built into each phone would do stage 2 charging

Awesome!!! its well worth it!!
Hello guys... I'm having a major problem with my battery not taking a charge or just being stubborn.
I used multiple chargers and the phone refuses to charge. It discharges even though it says it's charging and it mounts via USB with no issues and data transfer is faster than ever. I have the OEM stock and the Laza extended battery but the Laza takes much too long and the stock battery won't come back at all because the charger kills it...
This started when I left my extended battery on the charger overnight and it was at maybe 30%. I woke up and it was dead; it wasn't responding to anything unless I pulled the battery and it gave me the blinking orange LED. Any ideas?
*phone was dropped once but a WHILE ago
did nothing special and it was charging great 3 days ago
charging while powered down actually kills the battery FASTER
I'd appreciate any help.
Have the same issue. I believe my USB port is coming loose from the board and needs repair or replacement. I tried physically bending bits of the port with the battery removed to mixed success short-term, but now I have trouble just getting data to connect over the cable. Could try to work around the issue by buying a couple of wall chargers for just the battery pack, then circulate between two or three batteries through the day. Used Battery Monitor Widget app to see my device can eat 500 to 1,000 mA an hour, so I got two 500 mAh chargers and spare batteries to keep pace with max drain rate.
Okay, thanks for the recommendation! My Droid MAXX has arrived but my battery is actually doing pretty well right now. It decided to charge overnight but still no luck with the stock. But I still want to use this phone to test ROMs, and it's difficult to do so with the discharged battery. Anyways thanks a lot, I will look into this. Or maybe I could buy another Rezound for cheap or a Thunderbolt (if it works).
