If you make a transaction from electrum without using coin control, electrum minimize the number of used addresses and at the same time consolidate UTXOs that are assosiated with the same address.
Let's say you have three UTXOs in your wallet.
UTXO A: 0.01 BTC
UTXO B: 0.02 BTC
UTXO C: 0.03 BTC
UTXO D: 0.04 BTC
Assume that UTXOs B, C and D are assoisated with the same address.
Now, if you want to make a transaction spending 0.035 BTC (without using coin control), electrum will use all UTXOs B, C and D.
As already stated by Charles-Tim, use coin control to tell electrum which UTXO(s) you want to be used for your transaction.
Topic: How does Electrum decide from which of my addresses the BTCs are sent? (Read 27 times)
Charles- Tim has said pretty much. Now the way wallets work, they try to be efficient in the way they spend your coins and if you make use of an HD wallet which of course many persons use now, the wallet tries to save fees, and also spend your coins while simultaneously trying to make use of change addresses and sweeping to make your transactions more anonymous and difficult to trace. That's why every time you press receive on Electrum you get a new wallet address so your funds are not traced to a single address.
The idea of spending is your wallet looks for a single address that can pay for the transaction and if there's none it will consolidate funds from the available addresses, meaning you will have multiple inputs.

Can I somehow tell Electrum to use another addresses selection strategy?
Or even select the input addresses manually?
If you want to manually spend from an address or some addresses of your choice, use coin control.Or even select the input addresses manually?
On desktop Electrum wallet:
To access coin control, click on 'view' on the generally user interface and check ✔️ coins. The coin tab will appear which you can use to freeze UTXOs, addresses and to spend from addresses that you want to spend from.
On mobile Electrum wallet:
You can only use coin control to freeze address, addresses or coins but it can not be used to spend UTXOs.
Assume I have (simplified) the following addresses with BTCs on them
111111 with 0.100 BTC
222222 with 0.200 BTC
333333 with 0.300 BTC
444444 with 0.400 BTC
Now I want to send someone 0.280 BTC.
I go to "Send" tab fill in the target address and amount and click "Pay".
Now Electrum decides automatically from which of my addresses the BTCs are taken.
As far as I can see its always the addresses with the biggest amount. Here 444444.
Why ?
Why not properly do I cleanup and take the money from addresses 111111 and 222222?
If always the biggest amount addresses are taken then users will end up with thousands addresses with micro amounts.

Sorry for this newbie question.
