[AT&T Samsung Galaxy S II SGH-I777] Iskor12:
Bought one of these batteries. Shipping speed was actually decent.

Now onto the 3 F's

Fit / Form / Function

Fit: Battery fits just fine. Case fits very well....but there is a slight lip on the top left side.

Form: The feel of the phone is definitely different, but it's not bad.

Function: Definitely not 3500mAh, but for $9, I can't complain. Battery does seem to last much longer. I will post more on this when I've had more time with the battery.
[AT&T Samsung Galaxy S II SGH-I777] joeybear23:
Wow... that sucks.

I bought mine off Amazon for 12.99, and it was a US seller (I will have to look up the details).

I traveled for Thanksgiving and forgot my charger, but the phone lasted 3 days with 4.5 hours of display time. I always keep sync and data on, etc.

I was on UnNamed at the time.

Here is the seller I used:

[AT&T Samsung Galaxy S II SGH-I777] neikirk:
extended battery results so far

Got my battery and case (from eBay, as in first post in this thread), no boot loop, back fits fine. On third day of battery logging, so far lifetime seems only slightly better than my stock battery. On unNamed ROM 1.3.0, using about 2.5-3% of battery per hour for light to moderate use. On stock battery was also using about 3% per hour [although those test were only for pretty light use]. So far extended battery appears to be less than twice the capacity... but given the price not to bad.

Has anyone found a post about this battery damaging a phone? I'm tempted to try it, but I'm a little nervous about it damaging my phone.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
I haven't had any issues so far and I've been using it exclusively since posting about it. I also haven't seen anything saying they would damage the phone..
[AT&T Samsung Galaxy S II SGH-I777] mmarquis:
Mine (from eBay) has the boot loop

http://cgi.ebay.com/ws/eBayISAPI.dl...0&ssPageName=ADME:X:AAQ:US:1123#ht_1154wt_740

Awaiting seller's response.

Back looks great, fit is just a trifle off. Didn't try the case.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
Yup...that one has been reported to cause boot loops..

Stick with the one I originally posted. So far everyone that has purchased that one has had no issues.
[AT&T Samsung Galaxy S II SGH-I777] speedking261:
I'm intrigued about buying this as a backup/travel battery, but is there any noticeable performance increase. I see some people saying that it is about the same as the stock battery. Can someone take a guesstimate (haha firefox spell check recognizes guesstimate as a word) on how much performance increase they really get?

Thanks

EDIT

Hmm...I just read the product description "Best replacement for the original battery with comparable standby and talk time"

Comparable is not necessarily better
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Ordered this one last night, hoping for the best. If anyone has any more reviews good or bad, please share them!

Thanks!
[AT&T Samsung Galaxy S II SGH-I777] madquack:
I just ordered this combination that the OP has, I want to see how it feels, I mean for 23 dollars total, this isn't bad at all! I should get it around the 7th or the 8th which isn't bad. Will update with pictures once I receive the battery and the case.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Anyone still using this with no issues?
[AT&T Samsung Galaxy S II SGH-I777] gkeihl:
I purchased shortly after the op. Have not had any issues yet. No boot looping. The new back doesn't quite click on right on the top right, but the rest fits tight, and it does not fall off. I don't care for the shine on the battery back, but the case cures that. I feel it improves my life some by about 30%. Double size does not always mean double life .
[AT&T Samsung Galaxy S II SGH-I777] madquack:
I agree with everything said thus far. The top right doesn't mount flush with the the actual phone and the left side sits a little low. I don't care about the hump as its not as noticeable with the case on.

This is just holding me over until I can afford the Samsung 2000mah NFC battery. Bills are rough right now.. haha.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
It will mount flush it just needs a little more pressure applied to snap it in..
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
It took me 4 hrs to drain the original battery pack by playing games, and internet use. With this battery after playing the same games and similar internet after 4 hrs I still had about 40% left. This was a continuous 4 hours no breaks. I was off and figured I test both batteries and compare them. I had no honey do list so it was a "ME" day and yes I wasted it on this...The game I played mostly was Jelly Defense, so dam addicting and the fact it was a freebie on Amazon the other day was a win win.....
[AT&T Samsung Galaxy S II SGH-I777] madquack:
This was after sending/receiving 750 texts, downloading a 320mb chunk of data for a game called Starfront Collision HD, being on the web for a large portion of the day. The two upticks you see are from plugging my phone into my computer to upload some photos and probably beating 20 levels in angry birds rio, haha.

Overall I am highly impressed with this battery, it has more than surpassed my expectations as I was only getting 3 1/2 hours out of my stock battery barely using it.
[AT&T Samsung Galaxy S II SGH-I777] madquack:
Edit, for whomever has bought this combination:

Does your TPU case fit like a hooker that's been gangbanged by the entire NFL? I mean, is it super loose?? Is there any way to tighten it up at all?
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Wow, fits well both battery and case. Still have concerns about cheap battery exploding though. Does everyone that has this battery leave the phone plugged in all night? Anyone had any issues yet?
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
I keep mine plug in overnight when charging, sometimes phone is on or off while doing so. I also keep it plunged in when in the car. It never gets hot, so far I have been impressed with such a cheap battery. You can always shell out $98 for the Mugen it you like.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
True, ill stick to the cheap solution as no issues only success has been reported

Edit: just found a crack in the battery case. Check your batteries!
[AT&T Samsung Galaxy S II SGH-I777] Iskor12:
All night and every night since the day that I bought it. I'm liking this battery.

---------- Post added at 07:35 PM ---------- Previous post was at 07:14 PM ----------

Where is the location of this "crack"? I tore my battery appart...including taking off the sticker that wraps around the whole thing. I see nothing wrong with it outside of being cheaply made.

I took some pictures.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
So the plastic case isnt necessary around the battery?
[AT&T Samsung Galaxy S II SGH-I777] Iskor12:
The plastic case is only around the edges of the battery. The sticker and a thin piece of plastic is the only thing covering the Metal battery, which is still perfectly safe. I didn't tear into it anymore than what was pictured up above, but when I looked at it closely, it didn't look like it has any type of circuit protection, but I could be wrong. Either way, the phone does have a chip that controls that too, but the battery should have a fail safe.

Like I said, it is very cheaply made, however it does seem to be a pretty good battery. I am going on almost 3 weeks now with this battery. I keep it plugged in for 6-10 hours every night. No issues at all.

You do want to keep the plastic on the case to prevent shorts. The metal on the battery is likely Ground.....you definitely don't want to short a lithium battery, they can explode if you do...this is why there is plastic surrounding the metal battery.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Just got my replacement but how do you get the battery door to stay on? Seems I almost got it on once but once I want to remove it, it won't even smap both sides of the top of the battery case back in. The first battery was the same. Keep thinking I'm about to damage the phone trying try o snap it in.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
Mine went on relatively easy. I did have to apply a little more pressure to one of the corners to get it to snap in though.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Maybe I'll try that, keep thinking I'll damage the screen while pressing though. How much pressure is too much?
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
It didn't take a lot of pressure and I applied just to the corner so the screen was ok. the rest of the case snapped on easily so it was just the corner I had an issue with.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Okay, it seems to connect fine. Anyone had any battery issues to date yet?
[AT&T Samsung Galaxy S II SGH-I777] azmexmike:
Reporting my experiences ....

I jumped on the eBay pointer in this thread as soon as I saw it. Just to be sure I started off on the right foot, I left the phone powered down after dropping in the replacement battery and let it fully charge overnight. It worked great yesterday, the first day of use, and lasted most of the day - a great improvement over the stock 1650mAh battery.

Last night, though, I left the phone on overnight while charging. When I awoke, the display signalled that it was fully charged. But after disconnecting I learned that I only had 19pct charge! Here it is 10:30am in AZ and I'm swapping it out for the old battery.

This evening, I will power down and charge to see if that helps out.

Some people asked about the cover that comes with the battery. It is a tight fit, and kept popping off initially. I think it's settling in now, though. I bought the protective cover, too, and that turned out to be very helpful holding the cover in place while it settled in.

For what it's worth. Hope it helps. I'll try charging tonight while powered down and see it charges. I'll let you all know.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
Hopefully it goes well, keep us posted. I still have not had any issues with the 2 I have. Actually anybody reading this I have a Powerskin to sell. I used it for my comparison between this battery and the Droidax case. I don't use either and will part ways with it for $50. I will ship it free in the US. Just PM me...The Droidax I wont sell because I think its of poor quality.
[AT&T Samsung Galaxy S II SGH-I777] azmexmike:
Powered down and it fully re-charged overnight and has plenty of power to burn today. Odd that it won't charge correctly while the phone is on, though.

I didn't think of this before, but maybe there are differences between the various kernels and ROMs that might account for our varying experiences? I'm using UnNamed v1.3.2, the last version with UCKH7 baseband, and Entropy 12/8/11 (kernel 2.6.35.7, which I believe was packaged with the UnNamed version I'm using, though I do sometimes upgrade independently).

Anyone know?
[AT&T Samsung Galaxy S II SGH-I777] mmarquis:
A fix for the losse back

For what it's worth, my back didn't fit well at first with one of the top corners popping loose and not staying down.

I seem to have fixed it (at least on my phone) but putting the back on top first and holding it under tension a little while I pop the bottom in.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
I've been nervous about using this battery in fear it will blow up or cause damage but it looks like coast is clear. Dropped the battery after I opened and that made me nervous too. I suppose it can handle a drop

[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
you will need to use the battery cover that comes with the battery...Not sure how your case is designed. If its a complete shell unit then it wont work.
[AT&T Samsung Galaxy S II SGH-I777] Iskor12:
I never power my phone off and I don't have issues....this is rather strange.

---------- Post added at 02:52 PM ---------- Previous post was at 02:49 PM ----------

I really don't think that you should worry about dropping it. Overcharging it would be my biggest fear.
[AT&T Samsung Galaxy S II SGH-I777] mj0528:
Isn't there a built in feature with the phone that shuts off charging once its charged?
[AT&T Samsung Galaxy S II SGH-I777] Oretoise:
Bought the battery few days prior. Delivery scheduled for tomorrow or Thursday.

Judging by others' posts, this battery should be awesome.
[AT&T Samsung Galaxy S II SGH-I777] BigDogPooh:
Awesome!! Keep us posted on your findings once you get it...
[AT&T Samsung Galaxy S II SGH-I777] Hotfire1:
Even though this adds some size to phone, it still looks decent. Thank you.
[AT&T Samsung Galaxy S II SGH-I777] azmexmike:
I've been using the battery without incident for a couple weeks now. I love it. It is very rare now that I need to plug in during the day. It charges fully overnight without powering down. I bought the protective case, too. Given the odd shape after installing this battery - the phone sort of looks pregnant - a good, well designed case is highly recommended.

One final thought: My experience with batteries for cameras and other devices with proprietary DC designs is that the knock-offs often are built on the same manufacturing lines as the brand-name batteries. The only difference, then, is the silk screen markings that identify them as Samsung or Olympus or Canon or whomever. I've seen a few different off-brand 3500-mAh batteries mentioned here in Accessories. I can't help but wonder whether they're all from the same loaf of bread, so to speak. Maybe I'll mention this one level up and see what folks have to say ...
[AT&T Samsung Galaxy S II SGH-I777] Waddle:
The battery works great for me. It highly improves my battery life. At the end of the day with the old battery I used to have maybe 5% left. Now I have 40%. Thanks for finding this, and it's a great deal at 9 dollars.
[AT&T Samsung Galaxy S II SGH-I777] Terrold:
I use the 3500 battery. Came with back battery and universal wall charger. Payed 15 total. (Could have got it cheaper but I only buy in the states ...I work at fedex and I make entries on international shipments and I know they can be a pain.) But it was worth it. I can use my phone heavy through the day and get good battery life. I swap batteries when one is about to die and put it on the charger. 16 hours or so of heavy use and at 27%
[AT&T Samsung Galaxy S II SGH-I777] Bethrezen1453:

[AT&T Samsung Galaxy S II SGH-I777] BWheezy:
I also bought the linked battery and TPU case, ironically right after I ordered it my OEM sized battery and my kernel/ROM/etc flashes all settled in and my battery life went way up, more than I expected really. This will still be good for my upcoming trip to DC and other stuff where I absolutely positively need the battery to last all day especially with heavy use, and I'll probably be using GPS etc to wander around and find my way. I haven't used the phone a lot today but 9 hours and still at 83%...
[AT&T Samsung Galaxy S II SGH-I777] k1ska:
Been using the 3500mAh battery for over a week now and I haven't charged in 2 days, 4 and a half hours of screen time with wifi and auto-sync on, some bluetooth for FPSe gaming with my Phonejoy, some Samurai II, Osmos HD, and NFL Flick QB. I'm happy with this investment. :)

Edit: Still chugging along, 4% battery left and 5 hours of screen on time with 2d 1h phone unplugged time. :D

What are you looking to do?

If you are wanting to flash a new rom then download the rom of your choice. Boot to recovery, wipe everything except sdcard. Data, cache, davlik cache, boot, system, android-secure and wipe sd-ext if your card is partitioned.

Then flash the rom from the sdcard. Once finished, reboot phone.

Tegrak probably won't work properly if I'm correct set cpu or oc/uv beater should be fine. Tegrak was used for samsung processors. Qualcomm processors are able to scale better at lower or higher frequencies.

---------- Post added at 09:00 AM ---------- Previous post was at 08:55 AM ----------

It will never engage both cores that is asynchronous. Both processors work independently from each other. This is why you see lag. Both processors are never at their full potential. Qualcomm design the processors for best battery life in mind with good performance. There is a way to get both cores to be synchronized though if it matters to you. But expect worst battery life.

Hi,

I downloaded the non Verizon version of Skype and it doesn't let me use wifi at all. Is there a version of Skype that works with wifi on the Razr? Do I have to download the poorly rated Skype Mobile for Verizon to use wifi? Is it true that you can't uninstall the Verizon version of Skype?

Thanks for the help,

GP
[Motorola Droid RAZR] techfan2011:
Skype for Android works fine over Wifi for me. Avoid the Verizon version. It is my understanding that it makes Skype calls using the Verizon voice network and will therefore use your minutes. Skype for Verizon usually comes pre-installed on the system partition making it impossible to uninstall on non-rooted phones.

Any mention of video chat? On a sim free UK Razr here and skype from the market place doesn't doesn't have working video chat. It comes up with a message saying that its running on a non-certified device but that it should still work, and gives me the option to enable video calling.. but nada..
