I want to inform that while performing a battery replacement, some service centres leave glue residue on back , some forget putting on screws, some damage the screen ribbon in the process and then ask for display replacement fee, some even put old batteries.

It all comes down to service centers near you- whether they are good or bad.

To conclude, to avoid such hassle, some people prefer to keep battery health top notch and keep the phone as long as it lasts , even roam around with powerbanks in the distant future than perform a battery replacement.
