Hi There,

I've had my Note 9 since December 2018 and it has treated me very well. Still does all that I need to do, as fast as I need to do it.

One small problem - the battery life is fully shot. Having to charge multiple times a day. I tried a while back to see if Samsung would do this for me, but they suggested that I wouldn't get much of an improvement in battery life due to software updates etc. I assumed this was sales bs but have found mates to have battery replacements to make a difference.

Therefore - is it worth doing a battery replacement on this device? I get about 5 hours I think at the moment. I would be interested in your experience. Just to add, I've smashed the bank panel pretty badly (everything still works) so probably would want to replace this as well (as they are a fiver on ebay - again purely cosmetic).

Thoughts?

I did it 1 month ago. It's now waiting for the 3rd battery, been for 1 week in the shop. All the new ones ware manufactured in winter 2018 and were weaker than the 2900 mAh left in mine after 3 years, so no.

By the way, just got the new replacement. It's much better at 3600 mAh after one charge, and I could get around 6 hours of Revanced yesterday with 25% still left.

I'm just sitting here googling this very subject. My battery is still pretty good in normal usage, but struggled to get through a full day in a recent hospital stay (when, admittedly, I was using the phone much more than normal). Torn between a battery replacement, S23 Ultra in a few months, or stick it out for another year and hold out for the S24 Ultra. Note 9 is still perfect in every sense (I have the 512Gb version), it's just the battery life is starting to weaken. If, as you say, the genuine replacements are manufactured in 2018, I might just go for the third option and hold out for the S24.

I use AccuBattery for a long time. It estimates my 3 years old Note 9 battery is 74%. I go to service center and change battery. Now it's 100% after a few full charge. I feel significant improvement in battery usage, maybe 1-1.5 hours more on-screen time with same softwares, same usage.
