This is to do with what happens when the time comes (if it comes) to replace the battery of a mobile phone.

The discharge/recharge cycle with rechargeable batteries leads in the end (but slowly) to loss of rechargeability,
at which point the battery needs to be replaced.

I basically have a couple of questions:

1: If say 40-80% of the capacity is used each day, with full recharging at the end of each day (phone switched off at night),
how long is the battery likely to last until it needs replacement?

Varies widely. I find most modern batteries last a lot longer than they used to, and I can keep phones for four years or more. Though

since I have been buying Chinese ones from geekbuying.com I can afford a new one every three years. My Elephone 8000 had the

problem of compulsory diagnostics in Chinese, where I had to guess by bitter experience which symbol meant 'OK' and which

meant 'try again', the worst problem being the 'make emergency call' function on which I had to give a fast apology. But then I

got a Xiaomi A1 M1 with 'World' ROM, which is all in English and doing very well indeed.

I did get a new second battery for my Samsung 3 many years ago, and within a few years found both old and new batteries

equally good (both Samsung 3 and Elephone are still in action).

The nice thing about Chinese phones is that they all take two SIM cards, very useful when travelling and inded also in the UK

when in bad reception areas, so long as they are completely different.

> 2: During replacement, the phone is presumably totally without power for a short period of time. Can this lead

to information stored on the phone being lost?

Never been a problem for me.

Specifically, my phone is a fairly basic mobile, a DORO 6520. (And it has so far
been running happily for about 2 years).

Goole it. New batteries seem to be available for under £20.

(Though googling DORO 6520 battery returns at first hit an amazingly useless official 7-item help page)
