Samsung A3 2016 battery replacement. Worth the hassle?

    It's a nice phone. Not too big and does what I want it to., but at about 3 years old it is now showing battery issues. Taking a long while to charge and a short time to go flat.

    Batteries seem to be available for not much on Amazon or eBay and there are a few videos about showing how to do the job. It involves heating the glued on back then carefully prising it off, then removing the frame and finally pushing the battery out before fitting new battery and reversing the procedure. Doesn't look too challenging.

    Has anyone tried this?

    Not an A3 but done similar, yes it is straight forward. One has now lasted longer on the replacement battery than the original.

    Glad you said that because I've just ordered the necessary. Battery about £7, double sided tape for replacement, about £1.70, and a set of assorted plastic and metal prising and poking about tools for about £3.00. Probably don't really need the latter but they should make the job easier..
    So, if it all works out I should have a revitalised phone for under 12 quid.

    I had a Samsung Galaxy Note 4. I bought a brand new battery and it did not noticeably improve battery life. I bought a new phone a short while later. I don't have the technical explanation for this.

    I have done this three times on my wife's Samsung tablet. The first two times were using cheapo batteries from Ebay. With the first, the first time I charged the thing, the battery swelled up and started smouldering. The second battery last three months after which time it held no charge at all. The third battery, still working after a year was an OEM Samsung battery, cost alot more.

    Most of the Samsung batteries on Amazon and ebay are fakes, even from apparently reputable sellers. They'll do the job so no biggie. Always genuine batteries will be a premium price and come in proper branded packaging. If you want to know for sure there are sites which visually compare fake vs genuine (eg font type, spacing etc)

    Does the phone still get security updates? Probably not so I would not bother.

    As others have said, eBay full of fake batteries, they are dangerous, can cause fires and someone was killed in China when one exploded when he was making a call.

    I used genuine, would not, as said, trust dodgy copies.
    Did that once, many years ago, for wife's Moto. Razr, bulged and died after only a couple of charges.

    I replaced my A3 battery today.
    Getting the glass back off wasn't too difficult and a suction pad helped a lot getting the first little gap to get a plastic wedge in, followed by a credit card.
    Next stage was to remove the dozen or so tiny screws holding the main assembly into the frame, the idea being to get at the back of the battery to push it out of its recess. (It's glued in) Even with all screws out I could see no way of getting the frame and the rest apart and I wasn't about to start prising. So, I decided to carefully lever the old battery out, which I managed without damaging the phone, or puncturing the battery.

    Pushed new battery into place and tried to switch on but no power whatever. Then read the suppliers instructions to 'charge all batteries for 24 hours before use'. Plugged in and let it run until it began to show a bit od charge.

    Then after cleaning up as much old glue etc as possible, I used very narrow double sided tape where previous glue had been. Stuck back on and then carried on charging with phone switched off. Took about 3 hours to reach 100% but I'll keep it charging until 24 hours is up (Not overnight though.) I'd sooner be awake if it decides to self imolate.
    Got the battery from a Co. called 'GlitzyGizmos', who actually supply a UK phone number for querys etc., and operate on both eBay and Amazon.

    As an aside, whilst trying to remove old glue, I used Isopropyl, Meths, lighter fluid, label remover and white spirit. None worked. Acetone might have, but I had none, and it damages everything anyway.

    GG are the company who I was shocked to find supplied me a battery which came out as fake on close comparison with real one. That was years ago though, hope yours is ok.

    I've replaced batteries in phones before - using a hair-dryer to soften the glue makes the removal of the battery easier.

    Any Android 8 (Oreo) and older OS security updates are due to end later this year. So it worth considering before you go ahead.

    Still use a Nokia 3510i
    (check out that feature list!)
    Does all I need a phone to do but the battery is starting to fade at 17 years old!
    Trouble is that all the genuine batteries are likely to be as tired as mine and
    I certainly dont want to risk a new chinesium battery.
    Have no interest in a pocket computer that needs constant updates and replacing
    every other year because it cant run the bloatware anymore.
    One day a may update to a new dumb phone but dont hold yer breath lol
