Talktime
From Wikipedia, the free encyclopedia
Talktime is usually measured in hours for any rechargeable communications device (mobile phone or cordless phone).
This is the maximum expected duration a fully charged battery is expected to last under perfect conditions (ambient temperature has a major impact on battery life).
A safe rule of thumb is to use the following guide to expected talktimes as your phone battery ages (the last column has a specific example of 12 hours talktime):
| Age | fraction of max | percentage est. | talktime |
|---|---|---|---|
| under 1 year | 3/4 | 75–85% | 9–10 hours |
| 1–2 years | 2/3 | 66–75% | 8–9 hours |
| 2–3 years | 1/2 | 50–66% | 6–8 hour |
| 3–4 years | 1/3 | 33–50% | 4–6 hours |
| over 4 years | 1/4 | 25–33% | 3–4 hours |
Most phone batteries don't last more than 4–5 years and have to be replaced by then.
Talktime is different from the standby time of the device, which is always much longer.
