  1. Hey there. My galaxy s4 battery is swollen and anyone can tell it by just looking at it. But the main problem is that my phone won't turn on. It shows charging when connected to a switch. But when tried to switch it on, it just hangs on the samsung logo. I tries cache wipe and even factory resetting the phone. But the problem still persists. What do uou think? Would be great if you reply. Thanks ๐Ÿ˜‰

  2. mine doesn't spin as much as yours, but it doesn't hold a charge. any ideas?
    also any suggestions for battery types, Samsung S5

  3. I just replace them when they cant hold a charge anymore. Like for instance streaming a movie and half the battery is gone, time to change to a fresh one ๐Ÿ™‚

  4. After an hour and a half my battery goes from 100 to 30. Should i replace my battery? It was never like this before. Hopefully the battery i have coming in the mail fixes this issue

  5. My galaxy S4 active will work as long as it's on the charger, but I take it off of the charger and try to make a call or play a game, the phone will die within seconds, do I need a new battery?

  6. Buy 2 cheap* Samsung batteries and mark the top plastic piece with an exacto knife 1 & 2 (write small it's not easy). Buy 2 Samsung clamshell chargers and mark the batteries that come with them 3 & 4. Go to display settings on your phone and set your phone to show battery percentage.

    Your Samsung clamshell chargers will charge your batteries to 90-96% this is intentional because it's hard on batteries to trickle charge them for long periods of time.

    In order to condition NEW batteries: After you have charged them with the clamshell top them off to 100% with your phone but keep an eye on them TRICKLE CHARGING STRESSES Li-Ion BATTERIES! Use 1 through 4 until they die and every time you kill a battery put it on charge as soon as possible. You want to cycle all 4 batteries from 100% till it dies 2-3 times. After you have done this NEVER LET YOUR BATTERIES DROP BELOW 30% after conditioning which brings me to my "normal use" instructions.

    NORMAL USE: After the hassle of conditioning is over, you now have a system that pretty much gives you unlimited battery use while at the same time pampering your batteries to allow them to last longer. The reason I recommend 4 batteries is so you can have 1 in use, 1-2 ready to go, and 1-2 charging. When your battery reaches 30% remove it from your phone and pop in the next number in line. RUNNING Li-Ion BATTERIES LOW IS HARD ON THEM, after conditioning don't do it! Plus there's no reason to run them that low because you should always have one ready to go. DON'T USE YOUR PHONE TO CHARGE YOUR BATTERIES UNLESS YOU ARE "OFF-CHARGING" IT! If you do off-charge keep an eye on your L.E.D.! Immediately take phone off charge once it turns green. Charging your batteries while your phone is in use increases the heat of your batteries. Always using the clamshell chargers will ensure that you have charged batteries that were charged more gently!

    Don't worry about the fact that the fresh battery "isn't fully charged" anything over 80% is charged enough to get plenty of use out of it.

    4 btw, is the MINIMUM. For my Note 3 I run 4-6. I order enough batteries to bring me to 6 and when I get down to 4, I order 2 more. I have found that most batteries that I've been ordering last anywhere from 1 to 2+ years. I've had my Note 3 for 2 1/2 years now and I still have 2 batteries from my original set. I also used this same system for my previous S2, S3, and S4 so I know it works.

    * I don't care if they are counterfeit or not, I have found counterfeit Samsung knock-offs are a little higher quality than the ones with aftermarket labeling because they are closer to Samsung standards in order to pass them off as genuine.
    Btw, did you know you can buy a MHL (Mobile High-definition Link) cable from Ebay or Amazon for about $6 for your phone? An MHL cable has 3 ends a USB for power, a micro-USB for your phone and a HDMI plug for ANY flat screen TV. It enables you to watch movies on your TV from your phone even if it's not a smart TV.

    USE: Turn your screen down on your phone. This won't effect the display on your TV. The phone will use electricity slightly faster than the USB can charge the system. By turning your screen down the battery will last longer.

    If you have your Bluetooth turned on the sound will come out of your Bluetooth. If you don't want that to happen you have to turn your Bluetooth off.

    The S3, S4, S5 Active (but not regular S5) NOTE 2, NOTE 3, and NOTE 4 are the only phones that are MHL compatible. They discontinued this feature to sell more smart TV's utilizing Screen Mirroring. PLANNED OBSOLESCENCE SUCKS!

  7. My v20 went from 26 to 23 in a few minutes just browsing a tab. Turned it off to do the spin test which it failed and turned it back on to see it was 16 which almost instantly went to 13 when i went to plug it in. And just by coincidence on my old phone the battery was great brand new and conveintly became shittier with every "update" (lol what update it's still the same god damn android version with zero improvements)

  8. Brand new phone 1 day old. Losing charge 1% per minute whether I'm using the phone or not
    Not happy here. Going to try this. P. 's. It doesn't spin. It's not even 2 days old and loses aboutv1% charge per minute.

  9. i removed battery but suddenly my phone turned off and this video stopped .. at that time i've no idea what to do….

  10. Very useful informations. I have bought a phone which vibrates but doesnt turn on. And its a gaming phone. The battery probably overheated in games. Already bought a new battery. Lets see if my theory was right then ๐Ÿ™‚

  11. Today my phone just randomly turned of at around 8 a.m. and didn't turn back on until 3.20 p.m. later today and I had charged it,it's a Samsung galaxy j5 2015 if anyone knows what it could mean it is my mum's old phone so it could be up to 4 years old.

  12. Just came upon your site, in that I'm thinking of changing out my Motorhome batteries as well. I've got 4 golf cart 6V batteries, thinking of going with AGM this time. Wondering if I should add two more ( ) as I have a residential fridge that tends to pull out many Ah's from my system. I'm new to this lifestyle, so a ton to learn…nothing for wifi or cell boosting yet, so as I say, lots to learn.

  13. I have a Galaxy S4 battery that does spin but when charged it shows 4.26 on the meter, how can it still hold a charge and be a battery and does that mean that if it is bad the phone will be dead, with that battery in it and won't charge or turn on? Thanks, thumbs up.

  14. I have a phone that I don't know the brand of but the battery is spinning and I want a new one but the problem is the information I typed in google and it comes up only Samsung batteries and other random stuff..

  15. My dog spins like crazy every day, should I replace it or works only for batteries?

  16. This battery reconditioning program exceeded my presumptions. It worked on any drill battery, several AA and AAA batteries, and any camera battery. The steps are simple and the act itself is exciting to do. No matter what type of battery you`ve got, it is sure to function again!
