Keep Proxy Phones Running 24/7: Battery, Heat and Settings

A phone is designed to spend most of its life in a pocket, with the screen off and apps asleep. A proxy phone has the opposite job: stay connected and busy around the clock, often for months. Out of the box, Android works against that. This guide shows how to turn the phone into a reliable, always-on device.

Why proxy phones go offline

• Battery optimisation. Android’s Doze mode and app standby restrict background apps after the screen has been off for a while. A restricted proxy app can lose its tunnel.
• Manufacturer task killers. Many brands add their own layer that closes apps they consider idle, on top of Android’s limits.
• Heat. A hot phone throttles its modem and processor and may drop the data connection.
• Battery wear. Permanent full charge and heat age the battery, and a worn battery can’t cover short power interruptions.
• Updates and restarts. A system update can reset settings or restart the phone at night.

Step 1: exempt the app from battery optimisation

The Proxynator app asks for this during setup. To check it later:

1. Open Settings > Apps > Proxynator > Battery.
2. Choose Unrestricted (on some phones: “Don’t optimise” or “No restrictions”).
3. Make sure Background usage or Allow background activity is on.

Step 2: brand-specific settings

Menu names change between versions, so search the settings for “battery”, “autostart” or “background” if you can’t find an entry.

Step 3: turn off battery savers

• Turn off Battery saver and Adaptive battery (or “Adaptive power saving”).
• Turn off scheduled power-saving modes and “deep sleep” features.
• Disable scheduled power off and on, which some phones offer in their battery settings.

Step 4: protect the battery

Lithium-ion batteries wear fastest when they sit at 100 percent and when they are hot.

• Cap the charge. Many recent phones offer “Protect battery”, “Optimised charging” or an 80 percent limit. Turn it on.
• Use a moderate charger. A plain 10 to 18 W charger is gentler than fast charging for a phone that is always plugged in.
• Use good cables and ports. Loose cables cause charge interruptions that look like random disconnects.
• Inspect regularly. A phone that no longer lies flat, or a back cover that lifts, means a swollen battery. Unplug it and retire it.

Step 5: manage heat

• Remove thick cases so the phone can shed heat.
• Leave space between phones; a shelf or a rack beats a stacked pile.
• Keep phones out of direct sunlight and away from other heat sources.
• Turn the screen brightness down and let the screen time out; the app doesn’t need it.

Step 6: keep the connection steady

• Place phones where the mobile signal is strong. Weak signal means slow speeds and slow IP rotations.
• Disable automatic Wi-Fi if the phone keeps trying to join networks it shouldn’t.
• Check that mobile data stays on and that the SIM’s data allowance is not running out.

A weekly routine

1. Check the dashboard for phones that went offline and when.
2. Look at each phone’s last-seen time for patterns, such as drops every night.
3. Feel for hot phones and check batteries for swelling.
4. After any system update, reopen the app and confirm the battery setting.

Summary

Reliable proxy phones come down to a few settings and a bit of care: let the app run in the background, switch off the battery savers that fight it, keep the phone cool, and treat the battery gently. Do that once per phone and recheck after updates, and the phone will stay online with almost no attention.
